You ought to have two different versions of Media Player; teh fancy-ass skinned one and the incredibly simple one. Simply open them both up, and position the one you want to capture the picture of on the layer behind the other Media Player. To clarify, I do not mean cover up the first media player, but to have it where you can see it, but not be the active window. If you understand that, then you're pretty much sorted. Just hit print screen and paste into your graphics program =P
