Given the information there could be a lot of causes.
First I want to say I have a lot of qualms about codec packs. It’s because they install a lot of stuff and you don’t know how everything is going to interact, so pinpointing problems is very difficult. Also sometimes they don’t uninstall everything they install.
First you probably want to check if you can find a pattern among the video that display the wrong colors. Do they all use a certain codec (identified by the fourcc). Use
gspot,
avicodec, or
mediainfo to help you.
If it does stem from a specific codec, you could attempt to uninstall it (sometimes codec packs allow you to install/uninstall components - don’t know if K-Lite does though). If that doesn’t work, in gspot try using the render button at the bottom left (the little 1’s). You could be able to trace the codecs' dll’s and delete them manually (the object of this would be to install a different decoder outside of the codec pack).
One possible solution you could try is playing the files using
VLC Media Player. The player is clean and uses its own bundled decoders (independently of system-wide codecs in Windows); and it won’t associate itself with any file types unless you let it, and uninstalls very cleanly (no leftovers). So you could try that. (The results would be informative, because it would tell if it’s the system-wide codecs/filters in windows that render the video in the wrong colors).
Lastly, ghosting can also be caused by overlay problems.
The way to check would be to disable hardware acceleration temporarily. I typed out how to do it a bazillion times, but here’s
pics I found by googling to make it simpler. Play the file after turning off hardware acceleration. (Remember to turn hardware acceleration back on, because it takes a big hit on performance when off.) If it plays fine when hardware acceleration is off (without the wrong colors) you should suspect it’s an overlay problem. You could try adjusting the advanced hardware overlay settings for your graphics card (it’s usually in advanced display settings), or you could upgrade (or rollback) drivers for your graphics card (in your case the on-board Intel graphics chipset).
