You have to turn off hardware acceleration, then you'll probably be able to capture the screen shot and you won't get that black, or pink, image. The video overlay hardware acceleration uses a "colorkey" technique to replace a specific pixel color (usually black) with the video. Anywhere a "colorkey" pixel appears it will be replaced by a video pixel from the encoder. But this happens downstream from video memory, so if you do a system "print screen" it's taken from video memory before the overlay occurs and all you get is a screen shot of the "colorkey" black or pink pixels. Turning off hardware acceleration forces the encoder to write to standard video memory so your PC's print screen function will work.
Most DVD and video players for PC's have a screen capture option, if you use that rather than using the systems 'PrntScrn" function it will take care of that problem automatically.
But not in all cases, sometimes you'll still need to turn off hardware acceleration to make a capture. For example PowerDVD playing a Blu-Ray disk will not take screen captures, that function is grayed out, because hardware acceleration is turned on and you can't turn it off while playing Blu-Ray. So you can't get a screen capture using "PrtScrn" or PowerDVD's capture option.
But instead of playing "the disk" in the normal fashion you open PowerDVD, then select "media files" as the source and navigate to the Blu-Ray disk. Double click on the movies .m2ts file to play it, turn off hardware acceleration, and then the capture option will appear and you can do HD screen captures right from PowerDVD.
