Let's see if I can remember...
Cold Case, Desperate Housewives, Heroes, Grey's Anatomy, ER, CSI (sometimes all three), Without A Trace, King of Queens, According To Jim, Medium, Law & Order SVU
I know it doesn't seem like a lot but believe it or not, many ended up conflicting with each other, especially with the networks screwing with the start and stop times. It's one thing to adjust the default 1-min early, 3-min late timer, but when Grey's runs over 3-4 minutes routinely and ER starts 1-2 minutes early (both Thursday night, Grey's at 9pm and ER at 10pm), it gets messy. ER has been on a manual timer for a month or two now, missing the first couple of minutes. In the case of ER, it's usually a re-cap anyway.
As far as primetime TV, no, we really don't watch much of anything live. Only Grey's Anatomy (because my wife's co-workers talk it about it the next day) and Heroes ('cause I'm addicted to it) get watched the same night. Not live though. Maybe 30-min behind or an hour later.
I know. I'd have the option of (2) more satellite HD feeds though, hence being able to record, in theory, (3) HD programs at once. Right now, because of NO local HD via satellite, I'm limited to (1) at a time.
