The Long Goodbye and other Kino Video Blu-rays
« on: January 12, 2015, 02:30:05 pm »

For some reason JRiver 20 will not not play the DTS-MA 2.0 tracks.  All you get is silence.  I noticed this on The Party and What's New Pussycat as well.  Plays fine in PowerDVD 14.  All other DTS-MA tracks from other publishers play fine.  Any suggestions?

I just checked my DTS-HD MA 2.0 videos and they all playback just fine here. Build 54.

Thanks.  This only occurs on a few Kino discs only.  This also happened on Topkapi.  Strange but no big deal.

Only on the discs themselves?
Have you tried/considered ripping the movies into mkv?

I tried to get a copy of one of these discs, but the version I got has mono PCM tracks, and not DTS-HD MA. Sorry.
If you are using the dtsdecoderdll.dll for DTS-HD MA playback, make sure you got a "good" version, either 1.1.0.0 or 1.1.0.8/9, but not anything in between.

I was not aware of the difference in versions. I currently have 1.1.0.7 on all my computers.
What is the issue with the "not good" versions? I have not noticed any problems with playback.

I'll start looking for a download of the newer version, regardless, just to be safe.

They fail with mono streams, and seeing as my PCM disc uses mono, I could imagine the DTS HD one also having this configuration.

1.1.0.1 is the version you want for the highest quality audio.
 
It doesn't have the mono or 6.0 bugs that exist in other versions, and decodes lossy DTS tracks to 24-bit rather than 16-bit.
 
If I recall correctly, there is no one version with all the issues fixed - there is no version which decodes 2.1 tracks correctly - but this has the least compromises.
 
Ideally the decoders would output floating-point rather than integer values, but a 24-bit output is better than 16-bit.
 
Hendrik, let me know if you want a sample of a mono DTS HD track. My "Network" disc is mono DTS HD.

Can you e-mail me a copy (ver .01) or put a copy in your drop box? I can't find a copy (of any version) from a trustworthy source on-line anywhere.
Thanks

I have samples of those.

And fwiw, 1.1.0.8 decodes all important things properly, lossy to 24-bit, mono .. only 6.0 is not working to my knowledge, which i've never seen in any real-world sample.
The advantage of 1.1.0.8 is that its easily available, since it was shipped with TMT for a long time.

1.1.0.8 is definitely decoding "16-bit" tracks to 16-bit, while 1.1.0.1 decodes to 24-bit:


1.1.0.8


1.1.0.1

 
I don't think I've encountered 6.0 discs either, but it's still worth mentioning that 1.1.0.8 does not decode them correctly.
I think I got 1.1.0.1 off a TMT3 disc which was bundled with one of my optical drives years ago.
 
Those two issues aside, 1.1.0.8 should be fine though - other versions may have problems with mono or other tracks.

Apparently there is also a 7.1 channel config that everything before 1.1.0.8 choke on. There just isn't a perfect version!

Unless there is a specific 7.1 configuration, it appears to be decoding correctly for me in 1.1.0.1
I can't seem to find a 6.0 disc in my collection at all to test 1.1.0.8; I'm only finding 5.1 or 6.1 tracks.

You're correct that there is no one version that is "perfect".

Decoding lossy DTS to 24-bit rather than 16-bit tracks seems worthwhile though, if you have the option of using 1.1.0.1

I wonder, might it be possible to have LAV Filters automatically load a different decoder based on the track, or is that more trouble than it's worth?

Nah thats not going to happen.
I could patch the DTS header to force other decoders to think its 24-bit, but that doesn't seem worthwhile either really.

Considering that one of the strengths advertised for Media Center is that it uses 32-bit (or was it 64-bit?) decoders for lossy audio formats such as MP3/AAC, if that's something you are able to do, it might be worthwhile?
 
A lot of people seem to be performing DSP in their video setups (room correction etc.) so getting the highest quality out of the decoder initially seems like a good idea.
 
I suspect that the decoders only output integer, but it might be worth investigating to see whether they would output floating point?

floating point doesn't really offer any more precision than 24-bit integer, and some decoders just operate in int, especially for DTS, as the lossless modes all require integer modes.
