As you mentioned the new TV series Dave, I though it might be good, but it isn't really holding my attention, perhaps I'm looking for too much out of a Sci Fi series. I still maintain that Babylon 5 was one of the best, it had a running storyline, but each episode stood up on it's own.....Just my opinion, but I really enjoyed it, even on the third time of watching.
To answer your original question though, upgrading the PC is always good, anything to do with satellite reception can be technically challenging, so the world is your oyster.
