Can anybody tell me how to extract a particular paused-clip from a video and paste it in MSPaint?

I tried the usual PrintScreen technique from my Media Player Video but the picture goes black once I've saved the file.

Help! I've chosen some nice clips for Caption Competition Game but am unable capture them from the playing/paused episodes. smile
