I am extremely angry right now. Universal has let me down for the last time. I don't know why they can't seem to fix problems or learn from their mistakes, butI for one have had it. This started back with that lousy Buck Rogers set. I returned 3 of them before I got one without any scratches on the discs. I haven't watched it all the way through yet, and frankly, I'm afraid to. I purchased Quincy, and on the last disc it locks up. I was at Best Buy today, and noticed The Hammer Horror series collection. I picked it up, and on the flipside of disc 2 it locks up. It's not my dvd player, because I tried 3 differnt players, and they all lock up in the same part. I'm not getting an even exchange for Quincy, or the Hammer collection. I'm going to simply get a cash refund, and that will be that. The problem I have is this: I want these shows and collections on dvd, but if they are all defective, then it is out of my hands. I could exchange them multiple times to get a good set, but I'm through with that. I shouldn't have to. THE DOUBLE SIDED DISCS FROM UNIVERSAL ARE DEFECTIVE WITH A 99% FAILURE RATE. I will e-mail Universal soon, and update this thread with their response. Potential buyers beware.
