Okay, so I'm trying to watch a video and it doesn't play. Only sound. I was going to download the newest version of K-Lite Codec Pack but someone tells me CCCP is better. So I install that. Now my video plays. Good right? Well, now my 1080p movies are jumping and the sound is out of sync. So I install install the new K-Lite pack and now my video no longer plays and my 1080p movies are still jumpy and out of sync. Ideas? EDIT: Well, it seems my 1080p movies play fine in Media Player Classic, just not Windows Media Player anymore. I guess that's livable.
