Query: Great show, poor quality DVD

And I am not referring to the quality of the video picture-they were dealing with videotape and black and white kinescope to do the transfer. But I have had a devil of a time getting these discs to play. None of the four discs will play on my computer DVD drive. After about a dozen tries, I managed to get disc one to play on another DVD player, but it froze in the middle of the scene in the sixth episode and after that I could not get it to play again. I had to resort to my son's Playstation II to finally get disc 4 to play, and could never get disc 2 or 3 to play on any these three systems! I am heartily disappointed and disgusted, and am going to try to return my set for money or a set of discs that actually works!
