This is a very basic question I think I know the answer to, but want to confirm. I am thinking about picking up a second Tivo (I have a basic single tuner 80 hour Series 2) just to record one or two shows that come on at the same time. I believe the Tivo will work without the TV listings, you just have to manually preset the record info for the time and channel. Is that correct? I really don't want to have to pay the monthly fee for a second unit and think this would get me around that for the limited use the box would have. Thanks in advance!
