Hi i put that info on the webpage, but the DVD was through an Oppo 971h upconverting DVD Player connected to the projector through HDMI, set to 1080i (letting the projector scale it down to native 720p).
The Xbox360 HDDVD Addon is connected through the xbox via component cables @ 1080i as well.
I hate that we're in the middle of another format war. As badly as I want HD DVD or Blu Ray, I don't want to be stuck with one or the other when it tanks. I'll wait until they make a computer drive that handles both formats or a clear winner is named.
