My 3 year old DVD player began to have trouble recognizing DVDs when they were loaded.

It even plays really old, badly scratched CDs and DVDs without effort

Some of the reviewers had the same issues regarding DVDs and CDs just spitting back out of their laptops and after using this, it worked properly again

I ran the cleaning cycle of the CleanDr disc twice and have been able to read every disc I've loaded since, including scratched up public library DVDs

This worked better than the one I got from Radio S some years ago
