Before Tivo, I used to watch this comedy show, on local access TV. I like the fact that I can watch Ms. Divine's Show via TIVO as well even if I don't have cable.
It's a funny show, where she plays a bunch of different characters in these little films. She also does some improvisations as well. It's a weekly show and there is so much fun stuff to watch.
Her youtube link that I use is : http://www.youtube.com/msdivine
It comes great on my TIVO!
Her site is http://www.msdivine.net
There are other shows I am also discovering that used to be on public TV as well.
