It seems like quite a chunk of storage. Forgive me if I'm wrong, but I didn't think the official encode was more than about 7 gigs. However, if you've been able to maintain the quality of the DVDs, then personally I don't think it's excessive. Since this is supposed to be an improvement over the DVD, then anything up to and inlcuding a DL disc is fine. Hell, I just want to SEE it
