If you had direct tv tivo has a unit that replaces the driect tv tuner and will record two channels at once that's why I asked.

With the Tivo series two you can get a usb to ethernet adaptor and connect it to your network to get updates over the internet. The Replay comes with ethernet built in.

With the Tivo you can set it to record a show everytime it's one, everytime there is a new episode or everytime it's on including repeats. You can also tell it what shows you like and it trys to find other shows you may like and records them when it's not doing anything.

I set a season pass for shows I don't want to miss and give thumbs up to shows I like but don't care about missing then I always have something I like recorded.
