No official DVD but you can get a set of 2 DVDs from http://www.goldmonkey.com/ for $11.98. That's where I got mine. I'm very pleased with the quality. Not high definition by any means but pretty good. I believe these are copies from tapes made available to TV stations not burned off the air because there are occassionally brief black screens in the episodes where the commercials would have gone.
