Some nice stuff on your site man, but I have some friendly advice for you.
Basically, I would avoid PayPal like the plague - I know your site doesn't contain any adult content (from the look of the free images anyway) but PayPal are notorious for freezing accounts and withholding your funds as soon as they find something they don't like. And they do check.
You might do better to offer the videos for download instead, and use a processor like Epoch EU, who accept Switch & Solo cards as well as all the usual credit cards. The setup is a bit of an arse but they are a solid processor. That option would also mean you don't have to bother copying & sending out DVDs which can be a pain. I am just in the process of switching to downloadable movies on one of my paysites
I'm sure you've also thought about having everything inside a members area as well - Epoch can also set that up for you, and I think you'd make more money in the long run that way. Just keep the content coming and people will rebill month after month.
I might also be interested in helping you with marketing your site and transforming it into a proper paysite. My company currently has 5 successful sites, one of which is also smoking fetish based
Hope some of that helps anyway - drop me an email if you wanna chat.
