What happens is that on playback, there are blue and red dots/squares popping randomly all over the video screen. I have no idea why this is happening, but I figure it's a codec problem. I've used GSpot, but it tells me that all the codecs needed are installed.
I don't really want to download any codec packs since I had trouble with them before, so I'm wondering if anyone knows why I'm having this problem, or if I am actually missing a certain codec that GSpot isn't knowledgable of. Any help is appreciated.
Here are some screenshots:
