Catch-Up service not working on TiVo box
Just wanted to add that the same thing happened with our Tivo box at the same time you described, and sounds like it has with another user, Psum, who has made a similar topic.
Watching live TV working fine, as are our recordings. But catch up not working at all. Selecting catch up - channels, only has the iPlayer logo appear, all others have no pictures, just the text. iPlayer doesn't load, just an indefinite black screen if clicked.
It seems unlikely that (at least 3 so far reported) Tivo boxes have experienced hardware failure specifically affecting on demand/ catch up at the exact same time on the 26th. I expect it is more likely something on Virgin's end that is affecting TiVo catch up services and therefore will be fixed.
Hopefully anyway as we also have a lot of recordings.
