Followed the link:
http://epgstream.net/index.php/xmltv-guide-pack/
and it went nowhere, so I'm short on guidance. Looks like the mob the run the website are on extended sabbatical. The info on the site reads like IT help to me, where it's short on detail and generally assumes that you already know what's needed to make things work. I've run xmltvDownload and been able to fire up the configuration batch file. I can get a positive test connection and select the various channels I'd use but I'm left wondering where to next, to make it hang together with J River MC17.
Ok, am writing this as I do it, so here goes
Download the zip file from
http://epgstream.net/index.php/xmltv-download/ and extract it.
Run the configure file.
Back on the download page, click on the "Australia" link to open the details for oztivo.
Enter the "Channel URL" from the download page into the "Service" tab in the config program, then click "Advanced".
Enter the relevant details from the download page into the fields.
In the "channels" tab, select the channels and save.
(So you're up to here now)...
In the XMLTV tab, change the location of the XMLTV file to a desired one (Documents, perhaps).
Save those changes and use the red x to exit (the Close button throws an error).
Now run the xmltvDownload application. You should see it downloading data for all the channels you selected.
It will save this data to the file you told it to in the XMLTV section of the config app (you can check the file is populated by opening it in IE).
NOW in MC Standard View...
Drives & Devices > Television > TV Options > Load Program Guide.
Select the XMLTV option.
You don't need to run a file, so just enter the location of the file created by xmltvDownload.
You'll then need to pair the channel in MC with the channel on your guide (only once and this is just because the guide uses different IDs).
It should then import the guide data.
*One thing worth noting...
You can't set the xmltvDownload program to run once a day from the program itself unless you donate / register, but you can set it up in Task Scheduler in windows to run each time you start your htpc or at a particular time each day if it's always on...
Hope this helps :-) As you say, I don't use this myself but it seems OK and it looks like it works :-)
