i'm patiently waiting for all of the nickelodeon shows from the 90's: rocko's modern life, adventures of pete and pete, hey dude, etc.
Plus
mama's family
Freaks and geeks [it's out, though I probably won't scrap up the money for it for a while]
Frontline - PBS [do they count ?]
FYI:
.tvshowsondvd.com is the place I go to check if and when they're coming out.
the only show i own now is chapelle's show [due to its $10 price on day after thanksgiving] and i'll eventually get a few of the simpsons, most likely.
