Here are a couple of codecs we have found to be problematic. To determine what codec is playing your video, click on help, video codec troubleshooting, while playing or just after playing a video. To make sure a codec is causing a problem. Find the file or files and rename them. If your video issue goes away, you know that was the source. You can leave the file renamed, or rename it back and use a filter manager like DirectShow Filter Manger to unregister the codec. You can download DirectShow Filter Manger from http://www.easyworship.com/downloads/Utilities/DSFMgr.exe
