The first thing I'd try is blowing some canned air over the lazer 
lens. I just purchase a new DVD recorder. After playing a couple of 
DVDs without trouble, the video started breaking up on the next one. 
After I shot some canned air in there, it worked just fine. Must have 
been something on the lens.

You can also get a CD/DVD cleaning kit. The one I have includes a 
special disc that has some small brushes attached to the surface, and 
a bottle of cleaning fluid. The disc has a recorded audio program 
that tells you how perform the cleaning action.
