TiVo addict in the house here — and there is finally an app for the iPhone for my TiVo.

DVR Shows [1] is a 99-cent app, and while you can't control your DVR with it, you can see what shows are recorded and currently on your TiVo (as well as what's about to delete) when you're on your home WiFi network.

I'm still holding out for the app that lets me add and delete shows from my iPhone wherever I am, but baby steps don't bother me one bit.
