Are you talking about the 360 drive or the 360 HD DVD add on drive??
Hay, I am talking about the internal xbox dvd drive in comparison to the a2. The content I was viewing was a standard def. dvd of transformers.
The internal xbox dvd drive is supposed to have some upconverting capabilities. I always thought dvd's looked great on it, but they looked even better on my a2.
I will watch some hd dvd content on the player tonight or tomorrow.
