Thanks Daniel. It seems that even if a software DVD player application claims it will play HD-DVD, it "might not work" depending on the video card, processing power, Display, and display connection used (VGA or DVI or whatever). I'm already watching HD OTA programming on my PC so I know it has enough juice to display 1080 content. The content protection protocals the "industry" has imposed on HD-DVD and BluRay content makes watching them on a PC a 50/50 bet, at best.

The Xbox HD-DVD drive DOES play standard DVDs though. Of the 4 DVD player applications I have, one plays DVDs from that drive with the video "studdering" as if the film reel was out of sinc. One crashes when it tries to play movies from that drive. Media Player 11 works fine, as does VISTA's Media Center (which I'm assuming uses media center).

Is ANYONE actually watching HD movies on their PC with the Xbox 360 HD-DVD drive? If so, please tell me what software you are using, what your Processor speed is, and what video card/cable/display you're using. Thanks
