the freezing and crashing was an artistic decission I guess. I watched mine very closely last night and I don't seem to have any blocking freezing shutting down the dvd player problems. in chapter 26 tarkins voice does get quieter like some mention, I dont find it to noticable unless Im listening for it. no blocking up there either. freezes a second when changes layers after tarkin and darth are talking and he says "she lied" part. overall the movie seemed a little dark but that could be my tv. also I did notice which I think is my dvd player or tv on 2 occassions when c3po tells the storm trooper he was gonna take R2 for maintinence the background seems wavy and also when luke and leia are on the bridge before the swing across whe they are shown from far away frokm across the bridge. Like I said I don't think these are the disks cause I dont see it when I pay it on the computer
