Saturday Night Live on Netflix...?

So I like watching old snl episodes on my netflix account, but the episode all seem to be cut up/altered. I understand they cant do the Musical guest, but they tend to cut out skits entirely. For example in season30(i think) the episodes are only 30 mins long bu ton live tv there an hour. Also sometimes in weekend update or the monologue they cut time from those, its pretty obvious they do it too.
