From what I'm told, the fingerprint works differently and can somehow be attached/embedded as the member is downloading the video. This won't be a 100% indicator that the person that downloaded the video uploaded it but it's pretty damn close and can at least allow you to get rid of undesirable customers.

without actually thinking about it too much, I'd say that using a modified version of qt-faststart or equivalent that could add a metadata bit, which would be processed via a download script.. wouldn't use any server resources at all really - aside from disk space.. but you could dedicate a large tmpfs for that and have the d/l script delete the file after x amount of time (or when the download is complete... if you know how)...
Or something along those lines. Encoding full length videos, or even individual clips, on the fly would require much more than a single server for processing heh...
