I remember when the VHS tapes were reissued (I had seasons 1-6, i think, of the original releases) and I was told that they were the remastered episodes. Having seen a few of these episodes on a rare occasion when the local PBS station decided to grace us with them, I remembered not being verY impressed, and actually kind of dissapointed, so I passed at the time. Then the DVDs were released and I had heard rumors that they were also the remastered versions. So as I said before, I shied away once again.
However, doIng a little searching on Amazon.com, I seem to have been given a bit of hope:
Viola!
Namely, the following quote in the third Spotlight Review:
First of all, these episodes are the original ones shown on the BBC, not the "Re-mastered" ones that are available on VHS.
