drm costs a lot of retention - besides meaning that mac users can't watch the content. there are reasons that large gay sites stopped using DRM. of course, very very very few straight sites ever even bothered with it.

i have never made even close to as much per member with PPV as with paysites, and the guys i know who do make money with it still make more with paysites. i keep reading announcements that surfers are more and more turning to PPV, but i think that's probably just hype.

the most money made with pay per minute is based on a huge amount of content and variety. of course, you could try it both ways and see how it goes, but i doubt affiliates will flock to a single site offering pay per minute.
