Nope some of them sell the ORIGINAL DVD and include a CLEAN version on DVDr, they also use Adobe, and Sony software for the edits JUST LIKE MagnoliaFan and ADigitalMan and the rest of the usual suspects...

My sister turned me on to this a few years back (uber-Catholic) and she bought a few movies they sent the original DVD and a DVDr with a disclaimer in a paper sleeve as for the rentals according to a few of the companies the BUY an original for EACH rental that they send out - visit the sites and check out what they offer.
