you'd need something to playback lpcm tracks with HD-DVD. one of the cinemaster audio packs will give you a dll for this. blu-ray nicely seems to have AC3 tracks.
hopefully a new mpc will come out that can read the subs in the files as well.
i use mpc for playback of my HD-DVDs (when the drive isnt hookedup to my 360).
OK thanks for that. Is VLC Player any better?
