Is this affecting all channels and all future times? Or only certain channels in the future?
I'm trying to figure out whether you have a problem with your TiVo not getting a regular (every 5-6 hours approx) connection to update the guide and eventually all channels run out of data.. or if it's just certain channels, say, more than 7 days ahead (which can happen with BBC1 especially around the weekend).
The first thing is to try Home > Help & Settings > Settings > Network and make sure the box is connecting roughly every 5 hours.
If you can give a little more info, someone on here can probably help.
It's a problem unique to you because your upstream signal levels are out of spec and/or you have a box fault. If you don't report the issue to VM then how can they even be aware of it let alone resolve it? In this case you need an engineer out to rebalance the signal levels and/or replace your box. If you have broadband with VM, you'll get a V6 which is miles better than your current TiVo box.
I am sorry I thought you wee a VM person. I cannot get through to report the fault.
It's going to be quicker if you can wait on the phone. What I do is put them on speakerphone and carry on with what I'm doing until they answer. Failing that, the forum team will be along in a few days to a week, and they will be able to assist.
To ensure that customers get the best out of their services we would always recommend switching off the set top box at the mains on a regular basis to ensure that data is downloaded.
Just as a matter of interest, how often do Virgin CS recommend a box should be power-cycled? Personally - if a box is working fine otherwise, I'd have thought leaving it alone to operate reliably would be the way to go.
I know that periodically VM enforce reboots overnight, but I thought that generally coincided with software updates.
