My wife buys and uses the slip covers for DVDs (Her Gone With the Wind Collectors Edition DVDs, my LOTR DVDs, Star Wars DVDs, etc). We bought them at Walmart, cost about a dollar each. They kinda clip on the outer edge of the DVD/CD and cover the data side of the disc. We've never had a problem using them, no skip issues or anything like that...the DVD-ROM didn't like them, I should say, but the set top DVD player had no problem. I like them...
