screencapping in windows media player classic

Awhile back I found a tutorial on changing the settings so I can screen cap in Windows Media Player Classic but now I can't find it. I had to reinstall my kodec so now my settings are on default. I've searched through all the screencapping memories but I can't seem to find it.

Does anybody have the tutorial saved or know what I'm talking about?

Any help would be appreciated alot.! Thanks in advance.

Sorry this isn't really "icon" related but that's what i need the screen cap for.
