Thanks.  All crashes point to the same place, where I had some bug in BAT scanning.  I will figure out a fix tomorrow.

[Yaobing]

Please test this new DLL.  A bug that caused program to crash was fixed.

[tunes0710]

I left it scanning and popped out, but came in and it had crashed again.
This was using NIT and slow scan. Will try NIT and normal scan.
crash.dmp enclosed

[tunes0710]

It got up to 51/75 and crashed again, not selecting slow scan and choosing NIT.
Log enclosed.

[Yaobing]

Thanks for the logs.  Unfortunately you were only able to capture dump files, but not the logs.  For some reason the crash was so bad that the log files disappeared.  Something I only experienced since the last batch of logs you posted.

If you are not able to capture the log files, let's wait for the next public build and try again then.

[tunes0710]

I'll try other permutations to see if I can get it to crash but keep the log file

[Yaobing]

Build 45 is out on MC25 board.  Please just use that one.

[tunes0710]

Will give that a go - Do I need to re-download the other DLL from your post above, or just use the one that comes with .45?

[JimH]

Build 45 should do it.

[tunes0710]

Updating now... Have found out that if I run a scan and it crashes/removes the log, and I open it up straight away and do the same.. it keeps the log on the 2nd crash.

Will run a scan on the new version and upload a log from that too.
Log and dump come to over 1200KB, so emailing this.

[tunes0710]

It's crashed again, similar place using .45
Deleted log file, so re-opened and ran again - crashed in same place and left log file.
Again too big to upload, so have emailed to yaobing

[Yaobing]

Thanks.  I got it.  The NIT scan picked up transponders that do not carry any service, but are sending sections and tables.  We did not handle such cases properly.

Please try this DLL.

A good thing I see from your latest emailed logs is that we seem to get channel numbers in BAT, OpenTV channel info descriptors:

The above are just snippets of a large number of entries.  We get BAT sections only on one frequency, 11112000 kHz, transport stream ID 2067.

[tunes0710]

Brilliant news :-)
Have just done a scan using the new DLL and it completed successfully, no crashes.
Using NIT and slow scan.
Have emailed the logfile.

Let me know if you need me to do any other testing.

[JimH]

Thanks for your patience and help.

[Yaobing]

Great!  Thanks!

Now we got those nasty crashes out of the way, I will be able to concentrate on getting the channel numbers from BAT.  It will be a bit of complicated if BAT is only available on only one or some of the transport.

[Yaobing]

The BAT tables that we were able to scan so far do not help.  Not only they are not available on all transport, the data present in these tables do not correspond to anything in actual channels.

We got these tables using the standard DVB PID for BAT, i.e. 0x11.  Maybe this is the problem.  We have not been able to get the non-standard packets with PID 0xbba.

So I added some code to try a different method of getting these tables.  Please first install the latest (MC25.0.48) then copy the DLL.

[tunes0710]

Updated to the new version, replaced DLL and scanned using slow scan and NIT... it picked up an extra transponder somehow?! there are usually 75, but it picked up 76 this time.
Emailed logs

[Yaobing]

Thanks for testing.

it picked up an extra transponder somehow?! there are usually 75, but it picked up 76 this time.

Yes, there is a new transponder that was not there previously.  I don't think it is my change that caused it.  It probably is a new transponder.  It is transmitted with transport stream ID 2037, on frequency 12421500 kHz.

Notice that these channels don't even have channel names.  They just use "Service ID" for their names.

Now back to more important stuff.  We still can not get valid BAT data.  The alternative method that I added today did not produce any thing.

Are you sure FreeSat sends Bouquet Association Tables on PID 0xbba?  Nothing came up when we request packets with PID 0xbba, and TID (table ID) 0x4A.

[tunes0710]

Looks like a new transponder went live yesterday - it's mainly data apart from 1 BBC channel (so far).

With regards to the PID etc... this was the message from last month that the developer replied with.

You are probably looking at the wrong pid for the BAT data.

FreeSat uses non-standard pids for all the tables, probably because Sky got in first and used all the standard pids.

So the BAT is on pid 0xbba (not the standard pid 0x11) and you should find a descriptor with id 0xd3 which has the lcn info.

Looking at the log from EPG Collector, it say about getting network information data from 0xBB9 and station data from 0xBBA, so I'm assuming it's right?
I've also enclosed the log from EPG Collector in here as well if it helps?

[Yaobing]

Here is another modified DLL for testing.

I enabled some extra logging.  I am really puzzled.  EPGCollector indeed uses 0xbba for FreeSat PID.  For some reason those packets were not captured in MC.

Due to extra logging, the log file can be very large.  Do not use slow scan.

[tunes0710]

Just emailed latest log, using NIT without a slow scan.

[Yaobing]

Thanks for the log.

I am quite sure now we are not getting any packets with PID 0xbba.  Somewhere they are filtered out. 

[tunes0710]

Steve Kindly replied with me asking him if the PID and Table was correct

Checking my code pid 0xbba table 0x4a should be correct.

The source code is available on here. The module is FreeSatController.cs in EPG Collector\DVBServices\FreeSat.

I've uploaded the file.. as it references various dictionaries, I don't know if you'd need them as well, however the .cfg files are all available in his source code.
Hopefully this may help you?

[Yaobing]

Thanks for the info.  I have seen that file previously.  It shows that EPGCollector uses special PIDs.  But my problem is when I try to get those packets I find nothing.  I even wonder whether we really are tuned to FreeSat channels.

[tunes0710]

I think you must be, as for the actual viewing... it's freesat I'm getting....
If there is any other testing I can do, I'm happy to do so.. or if there are logs from any other software that would help.. happy to do that too....

You are sure the channels we found are FreeSat?  You may or may not be aware, we have not implemented DiSEqC inside MC.  It is on my list and I recently tried to restart the project, but have not gotten anywhere yet.  For now, you need to make sure the antenna is pointing to the correct satellite before you start using MC to scan.  The way to do it is to run another software that does have DiSEqC implemented.  If you don't ever switch to different satellite, then this is unlikely an issue.  Also judging by the fact you are able to run DVBCollector and get correct info, this is unlikely the issue.  But I thought I'd just throw it out there.

[tunes0710]

Oh god.. shoot me.

Talk about mixing my metaphors... The channels are actually Sky Digital... but Free to Air ones.
It is in EPG Collector that I specify Freesat, as the EPG is the same...
If you look on https://en.kingofsat.net/freqs.php?&pos=28.2E&standard=All&ordre=freq&filtre=Clear it shows that the channels are Sky Digital (with some also being classed as freesat).

However, it is the channel numbering from Freesat that I am after (i.e. BBC one being 101 etc)
I've included a couple of screen grabs from EPG Collector settings in case that helps? And also one from dvb dream.

Sorry! :-(

[tunes0710]

Have included a couple more grabs from DVB Dream regarding Diseqc settings...

I'm assuming it must be ok, as I'm able to watch TV via JRiver?

[Yaobing]

The channels appear to be the same, at least the one with details in a screenshot matches on in MC's scan identically.

So, if we are tuning to the same transport stream, why are the FreeSat packets not appearing?

Anyway, as a desperate attempt, I made a DLL that would look for FreeSat packets directly, without first looking for standard packets.  I do not see why it would matter, but I want to try anything.

Here is the DLL.

[tunes0710]

Ran it with the new DLL... it didn't find any channels, but I'm assuming from what you said, this was expected?

Have included the log that it produced.
Let me know if you need me to run it again?

[Yaobing]

I will keep looking for a way to get FreeSat BAT data.  In the mean time I added the following new feature (which you originally requested) to get around the problem:

NEW: Added an option during manual on-line EPG loading to fill empty "Channel Number" field with LCN value found in xmltv data.  Not applicable to ATSC channels.

This will be available in build 70 (not out yet) or later.

[tunes0710]

Brilliant :-)
Many thanks for that.
Will keep checking the thread, so if you make any progress with the BAT scanning, I'll test it out.

[tunes0710]

Will keep checking the thread, so if you make any progress with the BAT scanning, I'll test it out.

Looks like there may be a small glitch, in that the channel number overwriting the name of the channel.

For example "5 USA", gets matched with "5 USA" in the tvguide.xml, but where the LCN is 129 it's showing as "129 USA" on the right hand column
Same with "5Spike" becoming "141 Spike" and "5SELECT" turning in to "133 SELECT"

It works fine if the channel name doesn't start with a number
i.e. "BBC 6 Music" is (manually) matched with "707 BBC 6Music"

Also, the first time I did a channel scan and matched additional channels.. when I clicked next, it didn't import any of the channel numbers of the XMLTV ID numbers.
But after I went to load program guide and did it again, and it populated the details absolutely fine.

Happy to provide logs, but let me know how far you want me to go through the process before submitting the logs..
i.e. shall I recreate all of the above steps... or just do the initial scan and match (where it didn't show XMLTV IDs' etc)..

[tunes0710]

I just tried running it all again and not ticking add channel number to name.

But it's still stripping the number from the start of the channel name.
So for example, if I manually try to match 5 USA (which did auto match when I included adding channel number to name), it now just shows "USA" or "USA+1" in the dropdown, even though it is showing as 5USA in the TvGuide.xml

[Yaobing]

I see.  I had added code to prevent this from happening, but it does not cover the situation in which channel scan does not produce channel number.  For example if you had channel number to start with, your "5Spike" might be "141 5Spike", and stripping channel number would make it "5Spike".  But the program does not know the first part is already missing and ended up stripping the number in the second part.

I will think about it.

[tunes0710]

Hiya,
Just thought I'd check in to see if there was any update on BAT scanning, or the issue with stripping numbers from the start of a channel name?

Cheers :-)

No progress in getting info from BAT.

Regarding channel numbers, I did this:

25.0.84 (7/29/2019)

1. Changed: Re-implemented TV channel to xmltv ID matching routine for DVB channels as well as OpenCABLE and STB channels.  The more elaborate methods hopefully will improve matching accuracy, especially for DVB channels.

Hi guys,

Have only just noticed this conversation.

I too use Freesat, having dropped Sky a few years ago, but how these clowns get a license to broadcast sometimes is beyond me.

On at least a weekly basis and very often more frequently than this, they move channels around transponders and you only notice when a channel stops working and perform a rescan.

As tunes0710 has said, Freesat and Sky are both broadcast from Astra 28.2 - the only real difference is that any channel carrying any form of encryption will not be available to you if using Freeview.

@yaobing - For this provider at least (the only UK satellite one we have) it would be a godsend if there was an option to automatically identify encrypted channels in manage channels, then we could hide all of them at once.

As it is, I am so used to rescanning an reordering my lineup that I know which ones are encrypted, although over the past few months, they have been moving many previously FTA channels from Freesat over to Sky, meaning that they get encrypted so become unavailable to those of us using Freesat.

@tunes0710 - I tend to use the following transponder when rescanning, as it seems to the most reliable for me generally - 10714000 Horizontal, SR 22000, FEC 5/6, Modulation QPSK.

For checking listings, I would recommend Lyngsat and this has long been a firm favourite of mine. The listings available to Sky/Freesat can be found here - https://www.lyngsat.com/packages/Sky-UK.html

The site clearly shows encryption and other features with a colour code in the grid/table.

Due to the way that many of our channels work, there will be many examples that are duplicates destined for different regions and territories. An example of this is in the attached screenshot.

When scanning, the channel Really will appear twice, and MC will list these channels as Really and Really (1). From the Lyngsat listing, it is clear which version of the channel is for the UK and which is for Ireland, and then you can hide or remove the duplicate entry in MC by matching on the SID number.

For other channels such as Channel 4, this will appear multiple times for different regions, SD and HD and these will all just be labelled Channel 4 followed by sequential numbers.

It's the way they do it here I guess, but it is infuriating.

As for hiding vs deleting channels, I always just delete all the channels now and when re-scanning, I scroll down the list of new channels that populates the bottom of the manage channels list and can easily see which have changed or are new as am so used to doing it - again this is not due to an MC issue but due to the frequency that they are re-organised by Sky/Freesat.

I have previously tried to hide channels, but what I tend to find happens is that this also hides many of my existing channels that I want to keep, presumably because the name is the same.

Using Really as an example again, almost without exception, when scanning has completed and channels are listed in the manage channels grid, the Irish variant will be listed first as Really or ChannelName and the second variant (the UK one that I want) will be Really (1) or ChannelName (1).

I rename the channels so that the UK channel is changed from ChannelName (1) to ChannelName and for the Irish variant just add any random text to the end of the name to differentiate it and then hide it.

The issue I then have is that when I rescan channels again, all of the Irish variants appear again with no number after them as they get listed first. If I hide those channels that populate the bottom of the grid after a rescan, this also seems to hide the UK versions of the channels I edited previously to remove the number. I assume this is because both channels have the same name (the edited UK version that I called ChannelName now has the same name as the Irish version called ChannelName, and the UK version will appear again as ChannelName (1)).

If the channels do not get hidden because the names are the same then I must have some other problem, but every method I have tried seems to hide all versions of the channel that show the same display name, even though they are different channels as far as the SID is concerned.

Due to this, I just find it it quicker overall to shift select all of the channels, pick out the 3 or 4 I need to keep and delete the rest, then edit the remaining new channels and drag them to the correct place in the grid. I stopped bothering trying to number channels quite some time ago as Sky's system drove me mad.

Anyway, I hope some of this makes sense and/or is of use. Let me know if you need any further information or examples, screenshots etc.
