I see video codecs left and right. I have installed a couple of them, and I'm worried that maybe they are giving me trouble? I've been experiencing trouble playing some videos. They would freeze up with a white screen on start, but it wouldnt happen every time. Sometimes normal sometimes white. Sometimes they would revert to multicolor jibberish as well.. Is it only recommended to install one codec pack? Right now I've decided to focus on the klite codec pack.
