I had the same issue. What worked for me was changing my time settings. Somehow, it had gone back an hour - I suspect something to do with daylight savings - but if you put the time correctly the TV guide is back to normal and all works. Explains why the TV guide and live TV was affected.
Hope this helps some of you!
This is worked for me. I selected Ireland time zone and all seems ok
hope it helps
Hi. As others have suggested the time seems to be effecting it. Try changing the time zone in settings to Ireland as UK seems to be an hour behind. Hope that helps. If in doubt factory reset the box x
