Thanks for the suggestion! I tried switching over to WMP, but then some of my videos play pretty choppy. I did figure out a rather inelegant solution though. I've been re-encoding the problem videos with a program called "Avidemux." Re-encoding them to x264 fixes the issue. There's only a handful of my videos that have the pixelation problem, so it's not too much of pain to fix them one by one.

Thanks for the tip! I always use to install k-lite on all my new system builds, but for some reason totally forgot about it. Unfortunately, even after installing the mega pack, the issue is still there.

I just purchased Big Box and I too am experiencing the green/grey pixelation during the first few seconds of a few of my game video snaps. I have yet to find a solution but I think I've made some progress toward one. I decided to open the suspect videos directly in VLC and get the same pixelation during the first few seconds. However, the problem goes away if I go to the Tools>Preferences>Input/Codecs section in VLC and set "Hardware-accelerated decoding" to "DirectX Video Acceleration (DXVA) 2.0." Unfortunately, even though the videos now play fine in VLC, they still have the pixelation problem in Big Box. It appears that Big Box uses it's own VLC configuration file which is located in the main Launchbox folder under the "VLC" folder. I believe the line in this config that needs to be changed is "avcodec-hw=" and it needs to be changed to "avcodec-hw=dxva2". For some reason though I can't get the changes to the config file to be recognized in Big Box. Anyhow, I feel like I'm close to a solution and thought I would post here, just in case the above info helps toward a solution.
