I had first bought this on VHS from a girl at work 10 years ago through Avon. The quality was poor but I figured that's all that's available. I had seen some of the old shows on PBS and they all looked and sounded the same.  POOR  But when I saw the DVD I was overwhelmed. Superb quality both audio  and video. The clairity, detail and crispness of the black and white image  is unsurpassed. The auido is also excellent with no apparent hiss. This  disc makes watching B&W a new experience-Remember, this was taped  during the last days of B&W TV and it seems the B&W technology was  mastered. I have watched this over and over again. The performances are all  up to par by todays standards. A great Christmas treasure at a reasonable  price.
