I cant play HD DVD from my hard drive but i have some Blueray backed up that i can play. The blueray i watch is in 720p and the HD DVD is also 720p they are both in .mkv format the only difference is the HD DVD is x264. well i can play the HD DVD but the video and audio does not match up right the video is all laggy while the audio kida jumps periodically. i only have a 128mb graphics card(Nvidia Xpress 200) but i figured if i can play blueray properly than why not HD DVD. any ideas would be greatly appreciated.
