I was so thrilled to learn that this series was coming out on DVD--I loved watching the episodes on tv--when they played.Once I received the discs, I wa disappointed as several episodes froze in the middle and would not restart. This happened on two different sets (as I exchanaged the original set for a replacement).If Universal is going to sell double sided discs, they really need to quality check somewhere down the line.Shame on you Univeral for putting such a poor product on the market.
