OK, this is weird. Up until now I've been able to do a screenshot while a movie was playing on RealPlayer or Quicktime or what have you, and then I could paste it into a graphics program (I usually just use Paint) and save it as a static screenshot. Now all of a sudden I paste, and the image inside the player isn't static - it moves around, and saves as a black screen! WTF? Is this some kind of new copy protection or what?

Edited to add: OK, I got around it by changing the video acceleration settings, but that was just weird.
