I tried researching this, and in short, I found the answer to be this isn't possible. It seems whenever you try and grab a screenshot, it gets you just a blank screen. It wasn't clear whether this was intentional or just a result of the way the video is decompressed/played, but the analogy that stuck with me best is that of a projection screen; you can see the video, but if you try and take a picture of it with your camera, the flash results in you getting nothing. Just about every video player - Windows Media, DivX Player, DVD software - does this, so thats what leads me to the intentional vs. non-intentional debate.

Anyways, I know that some DVD playing programs have specific screen capture features. My guess is because the formats are open, its possible to write code to save the frame as an image rather than display it on the "projection screen." Real uses a proprietary closed format, though, so I don't think you'll find much luck finding a program that does this for Real videos.
