Last night I installed K-lite to get rid of a problem I had been having with my videos saving with a green bar at the bottom. Now, when I save a video in WMM, there is no audio and a lot of the clips are missing - its just a black screen. I'm sure it has something to do with the codecs, but I'm not sure which ones. It plays just fine on the time line, but when I save the audio is gone and clips are missing. Any help would be awesome.
