Here is the quick answer on your audio front, hoping it doesnt create a big discussion

. The HD DVD playback software on Xbox 360 is all new. My group implemented all of the a/v processing and various audio/video decoders. So there is no commonality between its performance on such things as DTS tracks and standard DVD playback on Xbox. The decoders are all very high performance and multi-threaded. The standard DVD was licensed third-party software. Of course, there may be bugs

. But we are standing ready to fix them. And since I manage that group and am active here, you should see much better response than other Xbox A/V related issues which I have no control over.
I thought HDMI was only supported in the $600 PS3 version?
