You will love it!! How many hours did you get? We got the 140 hours.. We record most things on atleast medium because the picture quality is lower so we use more space then we did on the replaytv (we had it less then a month and it broke) But it's been great.
It has completely changed the way we watch tv. We pretty much only watch stuff that is on the tivo-- the down side is, we don't ever watch the news anymore- and listening to cd's in the car.. we never know what is going on. I really like that I don't feel tied to the tv-- I don't have to worry about being home and there is always something to watch at 3 am. I also have no patience for commercials, the only downside I've found about that is that i don't see any movie trailers.
We had a few problems to work out at first.. between DH and I, we couldn't agree on the order of the season passes. We've since worked it out.. but it was bad enough for a few days that we thought about buying a second tivo.
there is a great forum for tivo-- tivocommunity.com They have alot of advice about getting started, tips and tricks, what's on and upcoming features. There are some really nice folks from tivo on there too.
Oh another thing-- check out the home media stuff. I set up the music server the other day and absolutely love it.. I can play music from my pc upstairs, on the stereo downstairs. It's been wonderful.
Have fun with it!
