Hello.
I realize that videolan.org can't allow for google adwords because it would introduce the spammers right?
Suggestion: create a banner on the main page "advertise here"
Then people can contact you and say "I want to advertise this program" so you can only show "selective" banners that are known to be legitimate.
Follow up suggestion would be to tell them to "make you an offer" for how much they'd be willing to pay to advertise there. Accept the highest bidder I suppose
This could bring in some extra revenue, and also allow for:
say I want to support VLC, I could advertise my [other] program for a month and thus get publicity as well as supporting VLC--win win for everyone!)
Anyway just thinking out loud.
Cheers!
