I'd like to take full screen frame grabs from movie files (mpg, wmf, avi). I began to do this by opening the files in RealPlayer, pausing, hitting PrtScr, pasting from the desktop into PhotoPaint and then saving. No problem. PC shut down. The next time I tried it the desktop image was blank. I switched to Windows Media Player, where it again worked. I closed down but again, the next time I tried I got a blank desktop image. Now I can't get frame images using either player.
Two questions ~
1, why was the frame image sometimes visible, sometimes not and why doesn't it work at all now?
2, is there any freeware that takes frame grabs from movie files and saves them to a file so I don't have to keep stopping to save the image in PhotoPaint?
