You should have a look to
http://www.skan-media.net about 38.000 Minutes of Videos to choose from incl. a lot of stuff for niches (all vids as MPEG or DVD)
and
you can get the stuff also as a leased gallery (wmv). You can set up your own video galleries by choosing from the whole videos we have, or just link to the ready to use galleries - as you prefer - it's starting at 30.- for 100 Members
