Had I owned the VHS tapes I might have kept them and not gone to DVD; but I only had a few and -- odd as it may sound -- I sent them to missionaries in Africa who are big Trekkies. I figured they needed a boost more than I. Thus my purchase (or getting as presents) of the beloved clamshells.
I guess I am glad that my not wanting a more colorful and clearer picture of a (great) '60s TV show befuddles people. There are many things I don't want.
