I have been using VLC Media player as my primary player for viewing videos for about a year. It recently stopped showing the video and just gave me the audio. When I closed LBC and restarted VLC Media player the video displayed properly. I've seen this behavior for wmv, mp4 and flv videos. Other media players like Windows Media Player, Adobe Media Player and QuickTime Player are not affected.
I'm on Windows XP SP3 fully updated.
I like LBC a lot. I hope that you can fix this quickly.
