As for those Clean Films-like peoples, they operate sorta like a Blockbuster. I'm not sure of the specifics (i'm against the idea of lazy individuals who feel compelled to "keep up with the jonses" but need those works sanitized to fit their limited sensibilities, but i'm all for the modification of films to fit alternative viewpoints) but I think you buy a copy of the film through them and they rent you the sanitized version. So your buying a copy and paying/renting for the edits. They've got special equipment which doesn't modify the original DVD (that's an obvious DMCA violation [anti-circumvention, which is a whole nother stupid legality]), they've got a special program which skips and does simple transitioning live.
Rikter, can you fit your uncompressed "Sanitied for Stupidity" versions on a CD?
