I have had major problems with my Season 3 set, it won't play 4 episodes without freezing up; 'Enos Strate to the Top', 'Hazzardville Horror', 'Good Neighbours Duke' and 'Along Came a Duke'. I have tried them on my Panasonic, Pioneer and Sony players and all show faults. The discs are brand new so there is no dirt or scratches on them. I think there has to be a pressing fault and it certainly doesn't help having these damn double sided discs! Are these common in the USA and the rest of Europe? I had never seen them before on UK pressings. The only way around the problem was to put them through DVD Shrink and make back ups of the 4 episodes. Thankfully I only paid just over £6 ($12) for each of the first 6 seasons! Season 7 is not out in the UK until September. I hope none of the other seasons are going to be so problematic as No. 3.
