Seems there is a "framing" issue (minor issues most people won't notice) but I was reading in the thread above about how it won't really take anything away from the movie, but it is something people should be aware about (for example, in BTTF 2 doc pushes a button on martys jacket to make it adjust to the right size, you can't see this on the dvd-release because it's mis-framed--things like this). I'm also having a seperate problem which I don't know if it's been adressed or not but (only tried the first disc so far) it locks my DVD-Player when I try to play it
Eitherway, it looks like they are defective but on a lighter note Universal looks like they're going to do something about it. Just a heads-up...
