Gammajo: I was basically quoting what Rick Walker told me. I assumed he was talking about a camera lens cleaning solution. If you find a specific solution tailored for use with a laser lens, you may feel safer using that solution, but I'd bet that solution and a camera lens solution are basically the same. I'm far from an expert on CD/DVD player problems and there seem to be more than a handful of troubleshooting guides for CD/DVD tracking problems that can be found on the internet. Sometimes tracking problems are caused by the discs themselves, other times it can be dirt or poor lubrication in the disc drive gears/rails, and other times it can certainly be dirt on the lens. Since the lens is the most sensitive of parts in your player, it probably should be the fix you try last. Just my 2 cents.
