I'm enjoying the hell out of these HD DVD's. I'm shooting them onto a 96" 2.35 screen with a Panny 900.

I've heard, but can't confirm, that HD DVD's really come to life with a 1080P projector or other display device. I'm currently taking the 1080P data and downconverting it to 720P. So I'm guessing that with a 1080P display, the difference between SD and HD dvd's will be similar to SD and HD TV programming.
