I am still learning my TiVo 360 (and I like it a lot!).
To my recollection (and I could be mistaken), part of the new 360 service is that if you switch on Tivo, you go to live TV and you want to watch a show on live TV that has already started (and is not finished yet), you could "watch it from start".
I was yesterday on ITV3+1 watching something but no matter what I've tried I couldn't find the option "watch from start". Does anyone know how do you activate it? Are there any restrictions to remember?
Finally, is there anywhere an option to watch ANYTHING, on ANY CHANNEL that has already been shown on air, for a period of say up to a week? (TV service providers in other countries have an option where you can stream from their service ANYTHING, on ANY CHANNEL, for up to week after it's been shown on air (i.e. you don't have to go to iPlayer, ITV Hub etc, searching for a show and having to go to a dedicated channel's streaming player).
To answer your first query. The Start Over feature is not available on all channels. Basically it's like pressing the green button on a freeview box on say BBC 1 and being able to play the current program from the start.
If you look at the EPG that have Start Over then they have a symbol next to them, a white anti clockwise rotating arrow with a play button inside it.
If it's greyed out then it's only available on catch up. Most BBC programs have it.
The picture below from Ziggo (VM's Dutch website) shows the icon.
