Off the top of my head, here is what I'm recording that is currently airing:

The 4400
The Dead Zone
Monk
Harvey Birdman
Robot Chicken
Justice League Unlimited (what can I say, I'm a sucker for superhero stuff)
Attack of the Show (but I don't recommend it)
XPlay
Family Guy
American Dad (occasionally as funny as Family Guy. I wish they hadn't rerun the pilot last night, though. That episode was horrible)

and lastly, This Old House Classics

I've got plenty others, but this being the summer season, it's limited to those shows. They certainly keep me busy enough, though.
