Are you looking to sell DVDs, memberships, or digital downloads?

From what I've seen, DVDs would be the safest, memberships possibly, but not digital downloads.

The "possibly" in both cases would be until some buyer would complain to them, as buyer's are known to do, then PP could play the "adult" card, even if it wasn't valid.

PayPal is very much "seller beware".

If you are selling DVDs, you should definitely do CCBill. DVDs are not considered "risk" by Visa, and therefore you can qualify for the lower processing rates and fees.

CCBill is the safest processor for memberships and digital downloads, although I have had very successful dealings with Commercegate.
