CC: There's no contract with Tivo. You buy the box, and pay a $13 monthly fee for the service. Mine is automatically deducted from my bank acct (b/c I would lose my mind if I forgot to pay it, and Tivo got turned off, :lol: ).
My tivo box tapes approx. 80 hours (the hours change depending on your record settings. Mine currently is set on "high", which is like the 2nd best, and so it supposedly tapes about 120 hours). Just like the Ipod, you can buy tivos with different memory space. More memory=more $$$.
I have about 10 8-hour VHS tapes I use as backups too, and when there are two or more things on at the same time. These have erasable labels on them, so I can update each time I use them! Fun!
