My only problem, on my 16x9 LCD, was some jagged edges on things...like there was no antialias. I noticed it a bit, particularly in the beginning of the movie. Other than that, I was prefectly happy with the movie. Anamorphic or not, I don't mind.
So, I went to the store and bought ESB and ROTJ. I haven't watched ROTJ yet, but I plan on doing it soon. I need to find something to do with the extra disks though.
