Microsoft filters out Windows Media screen captures?
Can anyone confirm this? I'm working here to convert some video that I shot of Jimmy Wales discussing wikipedia and was relegated to my Windows machine because of the file format. I attempted to use the Windows double-press Prnt-Scrn (its a button on your keyboard) trick to do an entire screen capture and then paste it into Windows Paint. Except, when I pasted it in Windows paint, I got the whole screen capture but where the paused video frame should be, it only shows a grey square. Has Microsoft gone out of its way to limit me from accessing my personally owned (soon to be creative commons) work? Below is a meta-screen capture of what Microsoft paint looks like on my machine. Of course, I'm just going to grab the frame from Linux now that I've got it converted, but this is a bit ridiculous.
UPDATE: mibus commented that this is just due to hardware acceleration. If you turn off hardware acceleration in the Control Panel > Display > Settings > Advanced > Troubleshoot, you can grab video. Thanks for promptly pointing this out. I should also note that with ksnapshot in Linux, it just works without tweaking anything. By Gary Lerhaupt, 02:02 PM in general | Comments (3)Comments

There's no conspiracy, it's hardware acceleration. Often, pausing the video first will de-activeate the H/W acceleration and allow a screengrab. If not, go into your advanced display properties and set hardware acceleration all the way down. The video will likely play badly, but should be screen-shottable. You'll see the same problem in most Linux software too - it's because the video isn't rendered into the window directly, but sent separately to the video card.
