tivo users: how do you change the default recording time on the tivo?

[pastrami]

We currently have basic cable service so we don't get all the channels, but for some reason 2-3 channels does come through, like the travel channel and food network. We can manually record these channels but it's only at 30mins increment, is there anyway to increase to 1-2hr blocks, so I get the whole show?

It's the similar to how the tivo hasn't called home in awhile, it won't know what show is on? You can still record but only at 30mins blocks, can that be changed?

I don't know why you could only record 30 minute blocks... if you set up a manual recording, it can be of any length.

And, if you want guide data for those channels, just rerun guided setup, tell it you have extended basic service (or whatever it's called), then mark the channels you don't receive.
