Mayberry Minutemen

I'll tell you this much though, admittedly, the quality of the episodes vary season by season.

Seasons 1-3 have pretty good picture, though you can kind of tell they're transfers: digital artifacts and pixelizations and such, but they're better looking than TV prints. Seasons 4 and 5 are kind of poor... 4 is particularly fuzzy and grainy, 5 isn't as bad, but the episodes have an orangish look to them for some reason. 6 and 7 are a lot better and look really good... and I'm guessing the rest are even better. I bought the slim re-release of Season 8 as a splurge (I have 1-5 in a limited edition gift set, and the original box-set releases of 6 and 7) and it's quality is really clear and sharp, as is GFA (I have that same set too: I was among the several who complained to 20th Century Fox about releasing the complete series set with special features after all those years of releasing individual season sets with no special features, which is why they temporarily pulled the complete series set from shelves and offered that GFA set as a substitute).

I once heard that M*A*S*H suffered from it's own popularity, from being reprinted over and over again for various different syndication markets, thus wearing the original master prints. Makes sense though. From observation, of the different classic shows I have on DVD, HOGAN'S HEROES seems to have been preserved the best, as its picture is incredibly clear and sharp.
