^Beatle - that is an outstanding
The Blu-Ray episode discs seemed to have the frame rate slightly adjusted so that when you ripped, they were slightly out of sync and had to be tweaked. The offset was different on each disc as I recall. I couldn't imagine why they would do that except to make it difficult to rip. I was merely doing it because I thought the disc navigation was annoying, especially the flashing icon when the effects sequences were changed.
Following Beatle's theory, they would be able to match particular edits to this collection when they found pirate copies or another CD issue from another country, etc. I notice there are already rips on mediafire and uploaded.to - if you google it, you might find them.
