OT aside, I think many of the technical issues that existed on the DVDs were likely caused by Lucas not giving them his full attention while he was still in production on Episode III. I mean, how else could we account for Luke's green lightsaber in A New Hope. The transfers were made from the 1997 special edition prints so the additional alterations made aren't set in stone. He didn't go back cut the newer Jabba model into the prints, he added them afterwards, which means these alterations can still be tweaked even if he's not doing a brand new transfer.
