Query: unusable DVDs

Do not buy this set. Other reviewers have noted that their DVDs were scratched, and this is absolutely accurate. Not only that but in 25% or more of the episodes, the DVD just freezes, and starts playing the entire episode over again from the beginning. There is no way to fast forward or skip the broken parts, and why should you have to? You paid for the whole season, but you'll be lucky to view 3/4 of it. A rip off. These are worse than bootleg copies from China. The distributor should be ashamed of itself. All buyers should get a full refund.
