As I alluded to in my response to thaumasiotes, I am perfectly aware that some compression algorithms are better than others. But, this whole conversation is being made with regard to counterfeit DVDs being passed off as the real thing. In such a case, something like H264 on DVD won't work in many players, thus the issue. The original scenario is counterfeits getting mixed in with official stock on Amazon. If the counterfeit uses a compression algorithm that works on all DVD players, it won't take any fewer discs as compared to the original. If the compression algorithm chosen is something more efficient (such as H264), and uses fewer discs, it won't work on many players, and the whole "I find it unlikely that a user, as opposed to a media company running stings, would ever complain" as voiced by thaumasiotes, is no longer valid.
