 Tested , Working wonderfully ( HD Quicktime  .MOV files )

 Download some HD Trailers and burn a CD insert it to Xbox360.

Tversity is too slow when streaming hd content.

I wonder How come they still didn't allow dvd upconversion through the component cables

oh and 007ybse04 did you use quicktime pro to save the trailers?

Hint:  You can grab the video from Temp. Internet Files Folder. of your PC

Or download another HD H264 Video form another sites
