Program that can record shared tectures?

Anyone know of a program that can record a shared texture to a video file of some sort? I know I can write a patch in vvvv to more or less do it, but then I have to go through the hassle of running multiple instances. I’d much rather use something off-the-shelf. Oh, and it needs to not need keyboard input to trigger the recording (like FRAPS); command line args would be best. Thanks!
