after more than half a day tweaking and reading and setting up...finally got my new HTPC to bitstream HD audio onto my AVR. but with a solution, come a new problem...
first, i only get HD audio with MPC-HC and not on XBMC for some reason. both Dolby TrueHD & DTS-MA works on MPC but on XBMC, all i get is PCM. whatever i try to do.
second problem, (i only have 1 TrueHD source) when i try playing the title with TrueHD using MPC-HC, the video playback is jerky...kinda like choppy...don't know what's the best word to describe it...but i play anything else, no problem, although there's another file with DTS-HD MA tat's giving problem, kinda like watching badly scratched DVD disk, or those Uncle Ho's DVD...
but the same title (with TrueHD) played using XBMC, no problem

but i can't get TrueHD or HD-MA...
i guess i'll have to live with it for the time being...perhaps anyone kind enough to let me know what's the problem?
i also read one net that Cyberlink PowerDVD comes with HD Audio decoder...i have a copy of the PowerDVD 8 that came with the BD-Rom i bought...i haven't tried it yet...maybe will update here later...
btw, i've tried MPC-HC, XBMC and MCE. MCE sucks real bad...i hated it the minute i started with it.
XBMC is probably the best, but somehow, not able to bitstream HD-MA & TrueHD.
MPC-HC, User Interface not the best, able to output both HD audio format, but a couple titles' video playback with its individual problem.
what other media center software is available out there? preferably freewares
