USA Network seems to be the only one with consistently flawed data. I've not personally had any problem with Comedy Central shows of late, but others might. Everything else is perfect.

The only problem I have with the TiVo about this is when there's a conflict. You can select which show is preferred, but sometimes shows change slots and you might not have set the preferences right. It'd be nice if it would prompt you when that happened so that you could verify that it was going to do the right thing or let you change it. If you're vigilant, this will never happen, but I'm certainly not that vigilant.
