I’m getting gaps in the programme information in the Guide on some channels, so am unable to set up certain programmes to record. This is the second time this has happened – I think the info eventually appeared on its own in the end before. I’ve done a channel re-scan, but it made no difference. Any idea what’s wrong please?

Have you tried a manual tune? See Link to manual tune FAQ
I’ve got the same problem.
Only recently appeared after a manual tune. I really do not want to repeat it as the last time I did it I missed a recording (auto or manual tune wipes the recording schedule).
As far as getting the missing info back, on both occasions I just left the box on, tuned to the ‘offending’ channel and the missing information was picked up and re-inserted just fine within 15 mins.
Box is running latest software and I’m tuned to Crystal Palace. A manual tune was done as ‘auto’ insisted on putting higher frequency poor reception mux first.
No I haven’t tried a manual retune. However, I’ve just checked again and the info is now there. Some of it appeared gradually as I watched. This morning the evening’s programmes were missing for BBC1HD, BBCHD and several other channels (not all HD).
I’m Crystal Palace too. So it seems the Guide is just flaky. Annoying, since a programme I had set to record next weekend had gone blank because there was no info and I’ve had to reinstate it. If I hadn’t noticed, who knows if it would have recorded or not?
Could a software update fix this?

Unlikely. If you go to Menu>Settings>System>Signal Detection then press the right arrow (to the right of the OK button) what channel numbers are reported?
Broadcaster problem was my first thought actually, but the latest example was odd. No BBC HD programmes on the guide shown earlier for this evening, but ITV HD and C4 HD programmes were there – and they are all on the same mux. Both current, afternoon and later BBC HD programmes were shown, so I think it is the same fault that the OP related. I’d turned the box on for the first time that day at about 1245.
The ‘fault’ mended itself within 15 mins, so if you had the box on, but were not looking at the guide, you’d never know.
Possible I suppose the guide transmissions currently have a problem at 0415 (or whenever the box has its daily look) but I’ve got an idea the problem last time was on a commercial mux.
At the moment, unless somebody says “it’s…” I reckon the best thing is to log the channel/s affected as at the moment, nothing to show whose fault or problem it is.
Just seen Martin’s post, sig strength about 66, quality 100 on all channels. All my channels are on the correct CP muxes as I had to do a manual tune to stop the box selecting the wrong and weaker transmitter for one mux.

Is that significant? Thanks for the help with this.
The guide doesn’t get refreshed overnight or during recording either. If you use autopadding every day you don’t boot the box you lose a day of forward epg. After 7 days the box will stop recording. Solution to this and having a full epg when you want it is simple. Use the power on/off timer.
Menu/settings/preferences/time.
I have Power On Timer 07:00, Channel BBC1-HD, Repeat Daily, Power Off Timer 07:20.

You should have only 6 and they should match your local transmitter .

A link to how to manual tune already posted.
Well, I’m learning a lot this afternoon! Let me check if I’ve got this right:
I need to do a manual retune to restrict channels to Crystal Palace only, but that won’t stop gaps appearing in the Guide?
What is autopadding? I have no idea if I’m using it or not. I just leave the box on standby and normally have a full 7 day Guide available (I think). But you are saying I need to set the power on/off timer to achieve this? So If I DON’T do this, setting a series to record for the next x weeks, for example, won’t work?

Confusing two different problems.
If you have channels from more than 1 transmitter it causes the problems you describe. ie gaps in the epg and failed recordings.
Other posters were describing the usual population of the epg which isn’t instant. If your box is in sby for two days and records nothing then when you next boot the box the missing two days will be downloaded to the epg. It will take a few minutes.
When you set a recording using series recording or a one off accurate recording then the box wakes up 15 mins before to wait for the signal to start recording. During this period the epg will update. If in the unlikely event of only having one series recording and the next event is more than 7 days away it will fail because the box never gets chance to get the extra days.
With it so far
In the menus the box has a setting to add padding to the scheduled epg times (early starts and late ends). This keeps series recording capability but turns off the accurate record capability. If you ask the box to start recording say 5 minutes before the scheduled time it can’t possibly know how much later the real start will be flagged. As a result the box wakes up at the scheduled time adjusted by the padding offset and instantly starts recording. Because there is no pre 15 minute period for the epg to populate the epg eventually runs out of data so the box stops recording. The solution as I already posted is to make sure the box is fully booted for a short period every day using the power on/off timer function.
Well this is fascinating stuff. Thanks so much for explaining it all Graham. I THINK I’ve got it.
I am indeed using padding, now I recognise what it is! I have it set to start 1 min before scheduled time and end 10 mins later, but I hadn’t realised that this turns off the accurate recording. This might explain why a recent Wimbledon overrun caused chaos with a scheduled recording. So I am better off NOT using padding and relying on “accurate recording” to adjust re-scheduled programmes automatically? I assume this is what it does? Then I also have he benefit of the 15 minute epg update.
Am I home and dry?!

Can’t tell if you are dry
, but yes you have grasped the nettle I don’t use autopadding at all but still have the auto on/off. It just means when you use the box for the first time in any one day that you have the full epg already present. Up to you if you follow the same practice. It rather depends on how you tend to use the box. If you specifically want to pad a programme (Channel 5 are crap at series recording). You can always set a manual repeating recording in the old fashioned way. For instance my better half likes to watch the lunchtime neighbours in the afternoon. I have a weekday repeating manual recording with pre and post adjusted times of 2 minutes. You do of course have to keep an eye on Bank Holidays etc.
OK, one more clarification please. If accurate recording will adjust for any re-scheduling of a programme (eg previous prog over-runs), I don’t need padding at all do I? The only reason I set it up was because that was what I always did on my previous (Panasonic) box which had no such feature, so I added 10 mins at the end of every recording in case things were running late. Is “accurate recording” reliable in your experience? Why would you choose to do a 2 mins pre and post padding?
