Just an idea... I'd like to try it myself but I don't have the programming knowledge nor the budget that would have to go into developing such a piece of software
Intro: (You can skip the intro) Don't know how many of you game - but the gaming industry (well particulary counterstrike) faced a big problem with cheaters probably around 2001. A program was developed called PunkBuster. You needed to have PunkBuster running on your computer (which would automatically update, and autorize you as a legit player) and do all sorts of checks to make sure you were not running cheats/hacks.
Video content can be protected by DRM, which is heavily, heavily flawed, and can also be easily worked around by using a screen recorder. Meaning someone with a legitimate DRM license to your video content simply has to screen record/capture your video to then have it unprotected.
So what is it? A video player that uses a specific video type (like how RealPlayer uses .rm) that authenticates users, similarly to DRM (so that only users authenticated with a Username/Password from your membership site can play the video) but also has a backend that checks to make sure no screen recording software/processes are running on your computer.
Benefit: Besides the instant protection of all of your new content, if everyone that was producing new, HD, premium content, started using it, eventually tube sites and the like would be left with all outdated/over used content...
Just an idea... on the other hand if it was implemented who knows if crackers/hackers would be able to somehow still get around it
