Well, that's why I asked...I wasn't sure...
He didn't use the HD version for ANH:R...correct? Except for a few select shots which he did indeed crop...right? (Example: Wedge flying around from ROTJ)
I just thought that if he'll be using the HD version for the *entire* film and then cropped some of those HD shots it would be noticable...but I could be wrong...I don't know enough about this stuff. :D
Edited: Thanks for the info guys! Good to know he can crop!
