I upgraded from 2.0.34 to 2.0.36 and notice:
1. HD playback via MPlay from an XP box is MUCH better. I record using TSReader and it generates a VBR "transport stream" - 720p was never a problem because of the low bitrate the networks enforce on their affiliates, but 1080i from NBC and CBS would always stutter and screw up the AC3 output on complex pictures. Now the filesystem can keep-up, all of these issues are gone.
2. DVD scene changes still screw up audio. The easiest way to see this is to get a copy of the movie Elisabeth - rip it and play the main movie. Within 30 seconds, there's a scene change in the VOB and that mucks up every time.
3. I used to be able to play M4A (Hym'ed iTunes content) just fine with the internal audio player. Now they kill playback. MP3 are fine.
So so close... Look forward to the 2.0 release.
