One more question. How will the sound for dvd's be from the xbox to my h/k 520 receiver be compared to a 200.00-250.00 stand alone dvd player to my receiver? Does the xbox pass as good or better of a sound signal to the reciever compared to a 2-250.00 stand alone dvd player?
Todd, progressive playback is possible (it was removed at the last minute in fact), but it's unlikely that they will enable it...an aftermarket hack might be a possibility, too.
The sound output is pretty much identical to a $200-$250 stand alone player.
