I found an Amazon user review that seems to match the complaints you mentioned, but always take Amazon reviewers with a mountain of salt. This reviewer sounds like a nut, and if a widescreen DVD looks pan n scan to him, he's either on drugs or doesn't have his player set correctly. Every other review I've read is completely glowing, so don't let this boob's review steer you away from this terrific release.
As an aside, though, Tim is a brilliant Bava scholar and commentator, but he's not the disc's producer. As such, he may have a commentary and be in the featurette, but the transfer and sound etc. would all have been supervised and controlled by other people.
