Hello, I've recently had to reinstall everything on my computer and have pretty much got it all together. However when I watch dvds in realplayer or windows media player I get a video picture which is fine but no sound. I know the sound setup is ok because I can play music with both players. Also I recently installed steinberg cubase v5 but get no sound from that either. I think the problem may be missing codecs but I really don't know too much about them. Can anyone help?
