yeah, I think that must have been to seriously preserve picture quality--as the job Warner's did on the theatrical version wasn't the best in the first place. I peeled off everything BUT the feature and shrunk it down to single layer to see how that would work, and there were some artifacts, but nothing too bad, certainly not enough to separate itself tremendously from the original dvd.

but just the film is around 7.5 gigs. That's not counting the extras he put on the thing. I'm sure you could separate them out to "movie" "bonus disc" and do two single layers, but if you're anal about watching compressed movies, you might wanna stick to the DL. Upping it as DL (or mailing it out) at least gives you the choice as to whether you wanna shrink it back down or get your dual layer burn on.
