On my (UK) copy of the DVD, if you try to play the video commentary on the widescreen side of the disc it tells you it only works on the full screen side. Does it work on the widescreen side of the US DVD? Or is there a audio commentary as well as a video one?
If the KSY Blu-ray doesn't have the bonuses, then that's really is bad. But I might still, and keep the DVD as well!
