I can't burn DVDs like I used to. Before I could have two or more clips on the one timeline I have, but I can't do it anymore. I can only burn a DVD if there's only one clip on the timeline. I get a warning box that says "unknown error: -12004" I even installed a new burner drive, but I get the same thing. Any thoughts on what might be the problem?
Someone helped me figure out the problem. I had chosen pcm audio instead of leaving it as dolby digital in the advanced options. After reverting back to dolby digital, it burns just as before.
