Well, I would take a screenshot but I can't get Fraps to work inside of the Windows Media Player. /arrgh

The images seem to imply that they are shadowing each other and lots of pixilation.

My guess would be that prior to the upgrade, maybe post-processing was enabled?

Does anyone know how to get Fraps or another program to take screen shots outside of a program? I'm still unable to resolve this matter and I would like to post a pic so everyone can see it. I'm just about ready to begin work on a new video idea but I can't watch any of the current videos on my HD without going crazy.

Thanks

These arn't videos I encoded myself, they are all AMS's off the website. The pixilization is killing me. Lawl ^^

Ok...the term 'post-processing' can also refer to a specific filter (or filters) that's in DivX's, XviD's, and ffdshow's decoder, that smoothes over stuff like grain and macroblocking (or at least attempts to) on playback. If it's enabled, it 'reduces' the appearance of such things, but if it's not enabled, you see the video in all it's unfiltered glory.

Example:

If the configuration screen for XviD's decoder on your system looks like that screenshot, then you're seeing the native imperfections in whatever video stream, if a decoder issue is the only thing at work here (if the Film Effect box is checked, you see it even more because it overlays a slight haze of static over the image to emulate watching film stock). The Deblocking and Deringing options you see under the Post-Processing section attempt to rectify certain problems, but IMO they aren't worth the amount of resources they take up, especially with how poorly they actually handle the job.

Changing the post-processing options didn't do anything to help the pixilization or the mirrioring effect. I'm completely stumpted. I gotta get a program to take screen shots.

The player software you are using doesn't have a screenshot feature? Or do those screenshots look OK and the problems are only visible during actual playback?

Capturing a screenshot in Windows Media Player
VLC Media Player and Media Player Classic both have a built-in screen capture feature that doesn't require the hoops you jump through to get screenshots from WMP.

Thanks for those tips Willian, I've never taken screenshots out of WMP so you can imiagne how baffled I was when fraps captured a black screen.

I've taken a few screen shots.
