The Muppet DVDs you speak of are (almost definitely) the Time-Life "Best of" collections. They are not the entire series, are without extras, and a few other little things not to like about them.

Fraggle Rock ran for 5 seasons, with a total of 96 episodes. Excluding the cartoon series, which I can't say how long it ran for.

Muppet Show also ran for 5 seasons, and had 120 episodes.

FUN FACT: In each country that Fraggle Rock was played in, the "Doc" character was played by someone else, and they had different jobs. In the US, he was a tinkerer working in a toolshed. In the UK, he worked in a lighthouse. In France, he worked in bakery.
