Failed to Record Ch4/E4/Film4
Been getting Failed to Record errors on the channel 4 channels over the last few days.
First happened for Ch4 News (SD, 4, 7pm) last Thursday or Friday and has happened on each Ch4 News since. Also happened for Mortal Engines on Film 4 (14, 6.40pm) on Saturday and Lego Masters Australia on E4 (13, 5.05pm) on Sunday.
In each case I've been around and lucky enough to notice in time enough to set up to record the programme on the respective +1 channel, and that worked, except today (see below).
I have two YouView boxes and since the first Ch4 News failure, which I usually only have on series record on one of them, I've set both boxes to series record Ch4 News on both Ch4 and Ch4+1 (to maximise the chances!), and both boxes have got Failed to Record errors on Ch4 for the last few days but recorded OK on the +1 -- except for today when one box failed on both Ch4 and Ch4+1 whereas the other box only failed on Ch4 but succeeded on the +1.
Both boxes are DN372Ts on 3.7.234/72.48.91, and I'm on the Crystal Palace tx.
Anyone else seeing the same or similar?
We are aware of issues with the D3&4 MUX failing to record on Huawei devices and are looking in to this with D3&4.
Are you able to confirm a few points for me to help narrow down the investigation?
Are only series recordings failing to record, or are individual recordings also failing?
Have any series recordings set after the 19th January failed to record?
Would you be able to reset all of your series recordings on one of your devices, and see whether that results in successful recordings?
Also, are you able to just set some recordings on channels not on the D3&4 MUX just to rule out anything else that may be going on?
Thank you again for all your help with this.
reading through your problem, of course the box will record when you have cancelled the series link & have then rekeyed it into the epg schedule. I have the same problem with Freesat (+ also happens at times with Freeview pvr) this week with another bug. It's mainly the broadcaster: itv/bbc/ch4 that have made the error. As much as it is very frustrating when recording fails, the problem is easily solved by following @Louise Murdoch link above. The problem won't go away until you cancelled/reset the series link.
The bbc have a habit of running a new series batch of BBC doctors after a short break & often you find the series hasn't recorded due to epg data not being updated correctly. I overcome this in advance by cancelling series & then straight away redoing series link so that it works. Only takes approx 10 seconds to do. Just have to remember to do it. Have fun! John L
Please do let us know how you get on with the recordings on your other device and I will feed this back to D3&4.
Yes, I have seen the issue you describe. But if the BBC have simply changed the Series CRID, then the ‘failed to record’ is just something that you notice, not anything that the box reports to you, because the box hasn’t seen anything wrong, just a programme going by and being ignored, like thousands of others, because it doesn’t match the Series CRID of anything in the box’s recording schedule.
@meyou2 is/was getting actual error reports on his Huawei, which is rather different.
Yes, appreciate this, but still unticking and reticking schedule hopefully in most cases will fix issue, until it happens again? My point really was @meyou2 was not resetting schedule as advised earlier. At the end of the day EPG data is input by someone at broadcaster. John L
None of our ‘simplistic’ theories would explain why Huawei boxes are affected by whatever it is, though, and Humax boxes aren’t.
It all points to some irregularity with the transmitted metadata on D3&4 that upsets the Huawei firmware, but doesn’t upset the Humax firmware; and we know from past issues that the two sets of firmware, despite doing nominally the same job, differ in some respects.
Thanks so much for testing this, and thank you for feeding back. Apologies resetting the series records doesn't appear to have worked on your other box. Would you be able to try a full retune of all channels?
We'd recommend removing the aerial, retuning (you'll see no channels), then replacing the aerial and retuning once more.
Might be worth trying on one box and testing, and if you don't mind losing the recordings on one box a factory reset, if the keep recordings options does not work.
While these are usually good things to try, i think that in the particular circumstances in which @meyou2 is helping YouView to tease out some acknowledged issues with D3&4 on Huawei boxes, I would not do either, unless specifically requested to by @Louise Murdoch
Also, just to rule out any clashing behaviour, do you have any other recordings set for the same time as the C4 News?
And again, many thanks for your thorough testing!
Interesting… IIRC, there’s one mechanism to let each tuner on your box have the Present/Following indicator (the flag that tells the box when one programme is stopping and another starting) for the channel it is tuned to, and another that provides all the Present/Following indicators, for all channels, so if your box/tuner is tuned to a different channel, it still gets the Present/Following indicator for the programme you want on another channel.
it sounds like the issue may be connected with this.
I think P/F is done by channel, though, not by mux. Though maybe it is by mux?
But would the YouView box still report ‘failed to record’, if it missed the P/F indicator entirely? Maybe it gets a sniff of it, but not enough to latch onto? 😛
