That's been my problem. Obviously, that's the first thing I did but it didn't work. Turns out the soundtrack isn't the exact length of the movie. It's a few seconds short. When you start talking about being a couple frames out of synch then it gets kind of tedious. Plus, I don't want to completely remux the soundtrack and video every attempt, so I plug it into Womble to check synch. That finally looks pretty good. I put it back into Encore, and I'm seeing the slight off synch. I'm actually doing the chapters now, then I'm going to render while I'm at work tonight. Hopefully it will be complete in the morning when I get home, then I'll check it out to see if it worked.
