Like a lot of people, I was overjoyed to find BRIDESHEAD REVISITED on dvd. But, I am now very frustrated with the set. The first one I purchased was defective, with the picture pixelating and freezing at the layer change on disc one. I received a replacement set, and I have just experienced the same problem on disc three, next-to-last episode. I have played both sets on my Pioneer 414 and double checked the defects on my computer. Same results. Has any one else experienced problems with this set?
