I can't access MF.com from work either. Anyway, the clips I uploaded over there are in xVid format and look better than they probably are in the real world. One thing that you can't see from the Star Wars clips is the telecine wobble, which is quite distracting. There's a lot of grain, and many, many film artefacts. On the plus side, the colours are less cartoonish than the 2004 releases and the audio isn't screwed. The sequels do look better than SW does, which is to be expected. Try these links.
