Sorry about not posting an update. Yes I have now watched Empire and Jedi and as far as picture/sound quality goes what I said about ANH goes for them too.

I've begun capturing and averaging, and am hoping to finish capturing / averaging side 4 of ANH tonight. I then plan to capture the VHS footage I need tomorrow night and edit the whole thing together. If I have time I will start Empire afterwards otherwise I will start Empire on Thursday.

It may not take me 3 weeks to do all the capturing and averaging after all! :D
