The plot thickens. I've just rebooted my 1T Tivo and the BBC HD 5.1 feed has returned. This has happened before in the past after a reboot. So is it a software fault with the Tivo after it updates and needs to reboot before it works properly or has the company that runs the feed for the BBC read my post and sorted it? I have not restarted the Tivo for quite some time so this may have been going on for weeks and only noticed no 5.1 about a week ago.
