I'm not an expert on the DTS disc, but it was created around the turn of the century as a method of recording 5.1 sound on standard 650MB cd. A standard cd player will reproduce a potentially speaker destructive stereo white noise, but this is actually a 5.1 dts encoded signal that can be decoded on the proper dvd player / receiver combination. I have several of these in .WAV files, and a few that are in .DTS files. I'm able to burn the .WAV files with no problem. They play 5.1 sound as expected.
I'm able to burn .DTS files that are sampled at 44.1k, but not the higher sampled 96k files. That makes me think that the sample rate is the problem.
Here's a line from the log for one .DTS file that I've burned successfully:
I 15:43:53 Writing Track 1 of 1... (AUDIO/2352, DTS, LBA: 0 - 16949)
Does that mean that .DTS is recognizable for DirectShow, and therefore a different filter is not the answer?
Also, does my audio file have to be 44.1k 16 bit?
