Star Trek: Next Generation (double episodes)
Star Trek: Voyager (double episodes)
Star Gate: Universe (only just started, double episodes)
James Mays Man Lab .... sort of. It gets a bit too silly sometimes.
MythBusters. Because it's science made fun!
Monster Garage. Just for the occasionally very awesome vehicles they turn out.
The ZOO. Cool show about a Zoo in New Zealand and what they get up to from day to day.
Other than those, the news and the occasional movie, I don't watch a lot of tv.
