You can get screen caps from Windows Media Player. Tools->Options->Performance->Advanced and uncheck "Use overlays" under the DVD video section. :) Nice YTMNDs btw.
Pretty cool. And you can also do this in realtime if you set up a virtual webcam and do a printscreen of something in the YV12 hardware overlay for displaying video. You'll get a repeat of what's on screen and so on. Neat sh*t.
