It also adds a "login in once with your TiVo.com account, use anywhere" feature, which is touted after first launching the app after updating. Unfortunately it doesn't work. After logging in with my TiVo account at home, when I went to my office (WiFi) and launched the app later in the day, I was told it couldn't find any devices on my LAN and asked me to log in again. So much for logging in once.
As for the "What to watch" feature, at first glance I guess it could be somewhat useful to some people, but I'll probably never use it. It's annoying that it always opens to that page when starting the app.
