My Samsung DVD Player has started to skip and so I thought I'd give this a try. It's easy to use, just turn on your TV and DVD Player and then insert the disk. It will show you a menu and I just selected the "Clean" function. After about ten seconds, it's done and you can eject the disk. Only time will tell if this really works. The DVD recommends cleaning every ten hours of use. I'll test it out on a few DVD's and report back.
