I'm back....
Well, it's now 10.10PM 13/12/17 and the message on my TiVo says "Wed 13/12 Program info has run out"

The last message told me that it would do an attempt at Wed 13/12 9.54PM

HOWEVER looking in Network, it says it progress is at 78%, so I assume, it is doing the auto update/9.54PM job to fix itself?

When I look in the guide, many things simply say "to be announced"..so it seems to run right down to nothing before it refreshes?

Dunno if this is right, but????
