Any idea why all BT Sport channels have the message 'to be announced' ? I've tried to switch off and re-start the system but still not giving any description of the programmes, so I'm not able to record
How far in advance do you have BT Sport listings currently? They should be going upto Saturday 14th @ 06:00 at the moment.
If you're missing anything prior to that, then you could be missing other guide data without realising, so you're best off updating your whole EPG via Home > Help > Settings > Network. Give the box 30minutes or so to complete the process then recheck the guide.
