Just got this disc (R2). Superb film, without a doubt the best thing GG has ever done. But there seems to be a glitch with the audio selection. Doesn't seem to be a 5.1 sound track? In the disc setup, it's there, but selecting it still only gives DS. Anyone else noticed this? I haven't as yet tried manually turning my amp to 5.1. It's on 'auto' selection.
