Have you ever heard of TokenSystems? I have been using them for a long time now and I believe their system is the best way to charge for your content.
It is a pay-per-view AVS company and you can charge a couple dollars for just one movie clip and believe me, PEOPLE WILL PAY IT! Save your bandwidth charges and don't give your whole site away for $20-30 a month. Make a couple dollars off just one movie clip!
Here is some more information:

P.S. I don't make a penny from that link above, I just wanted to tell you about TokenSystems, because of PayPal canning all adult accounts.
Thank you.
