Not sure what exactly you mean by "which surround mode". I have my Denon set to Standard, then when playing a blu ray I usually play the hd track. If watching a standard dvd I usually play the DTS track Dolby Digital.

I have both movies so will give them a try. I bumped up the volume on my rears last night so will give it a test.

For Casino Royale, you wouldn't know what chapters those scenes are in would you?
