The TiVo software feels ancient
For me it's a bit bizarre how well TiVo are doing, given how archaic their platform is for the user. The UI is unbelievably slow. 9 seconds to redraw a screen. Scrolling through menus, it can't keep up with button clicks. It's also flakey; roughly one time in four the EPG won't give programme details are allow me to request a new recording. Some of the UI is in HD and some isn't. TiVo has its own app platform, but they live in a separate ghetto off the main menu which is rarely visited, and they don't integrate into the TV experience.
This standard may have been acceptable 11 years ago when I got my Series 1, but is shocking if you compare it to the experience from a modern smartphone. (Speaking of which, they've been promising us an Android app for years, but it's still not available.) Now we see the XBox One can snap its apps over the TV feed, it just rubs in how far TiVo is from what it could be.
