I used to play the hell out of this...back on the original xbox on a standard tv. I recently decided to fire her up on the 360 on my HDTV. I notice that the game only plays in standard mode. Does this game support widescreen (I know that other xbox games do)?

Both RB6-3 and R6-3 BA didn't support widescreen; R6V was the 1st R6 game on consoles that did.
