goal: playback mkv with untouched video+audio+subtitle, movie only, no menu/bonus.
wdtv live issue:
1. can't passthrough dts-hd ma, truehd only
2. chapter not working with remote prev/next button
3. embedded PGS subtitle not working
so bought a PBO with + chip, installed a few custom firmware:
ACRO 7.3.4 r4824:
1. hd audio passthrough not working!
MedeBO latest, ACRO 7.4.4 r3966 & r4585 & r5440:
1. hd audio passthrough works! including dts-hd ma
2. chapter button works!
3. embedded PGS subtitle not working, same as wdtv
4. stutter issue with some high bitrate mkv, same mkv worked fine in wdtv live :-(
5. when playback, display or subtitle button pops up overlay message, sometimes this would cause stutter, audio drop; no such issue with wdtv :-(
I'm not sure 4/5 are firmware issue or not enuff CPU juice in PBO?
