Just been having a browse of www.dvdcompare.org.uk. It seems to supply quite comprehensive descriptions of differences in content between different DVD versions of the same film. But (for the films I've checked out so far, anyway) it doesn't seem to have much to offer in terms of quality comparisons - which version actually looks or sounds better because of the way it has been mastered. I would like someone to tell me "the NTSC version is particularly prone to NTSC motion aretfacts" or "the PAL version has especially objectionable sonic artefacts", and so forth. Can anyone suggest a good place to find quality comparisons like this?
