<p>I am having problems with video playback. The computer is new and has windows 7. Latest download of openlp. All of my videos work great in wmp. They are mov, mp4 and mpg files. I have toggled the VMR option in openlp and no luck. I either get the error: "codec error occured playing video" or something about pins. The best I get is audio to play back but a black screen. Again they all work in wmp. Any thoughts? I really want to use this but we tried going live and had no video playback.</p>
