Blu-Ray is going to be using AVCs from now forward on most of the newer movies coming out. I tihnk the majority are going to be in MPEG4, VC-1 is great for compression that's why HD-DVD uses it, but when you use 50GB discs standard you don't need to compress as much so MPEG4 will likely be just as good quality if not better. The Majority of Porn sales are over the net. Think about it, I can get a subcription to a family of website, like 10-20 of the same brand for 20 bucks a month. I wil have access to all their movies, archives, and new movies. What can I get movie wise for 20 bucks? 1 DVD in 480p, which I could burn myself from my computer when I download the movies from the net. Who would ever buy a movie on DVD? It's been a continuing downtrend since VHS. When VHS was introduced the net wasn't around, and individual porn movies could sell in the millions of copies. Now for individual movies that is no longer the case. HD-DVDs and Blu-rays will sell even less. Would you really pay 50bucks for those? Yeah right when you can get it basically free on the net.
