Won't record BBC1HD

Since about the start of May 2015, my YouView Humax T1000 box has ben refusing to record programmes (singly and as a series) from BBC 1 HD. BBC 1SD is OK as are all other channels.
I have re-tuned the box. Still won't record
I have done a reset from Settings. still won't record
I am tuned to Beds/Cambs as it has the best signal (70%/100%). Other choices are East Midlands and Yorks/Lincs, both of which are 40/70
Any ideas?

Please post your aerial type (loft/roof etc) and both your signal strength and quality %.
COM8: NEW FREEVIEW MULTIPLEX
In May, an additional commercial multiplex of channels for viewers with a Freeview HD device, EE TV or YouView box is being rolled out in further locations. Multiplex COM8 currently only carries QVC+1 HD and QVC Beauty HD on channels 111 and 112. There is sufficient capacity for further HD and SD channels.
COM8 became available during April 2015 in parts of London (Crystal Palace transmitter), the North West (Winter Hill), West Midlands (Sutton Coldfield), Yorkshire (Emley Moor), Central Scotland (Black Hill), Bedfordshire and Cambridgeshire (Sandy Heath) and Somerset (Mendip).

Signal strength is 50-55% and quality is 100%. I checked channels 1 (BBC1 SD), 101 (BBC1 HD), 102 (BBC3 HD) 103 (ITV HD) and 107 (BBC News HD) amd they are all about the same
Film4 +1
BBC2 HD
ITV HD
CH4 HD
BBC3 HD
CBBC HD

Will you test record one of these channels trophy, to see what happens.
How, exactly, does it refuse to record them? Does it refuse the record request, and if so with what error code, or does it accept the request and not carry it out, appear to record but produce a blank one, or what?
Could a new 4G mast have just been switched on in your area, and you will need a filter for this?

If so, note the comments there about fixing this issue on communal aerials.
Re the multiplexes in the list that Visionman gave, some of the HD channels you reference are on Com 7 not Com 3, such as BBC News HD and BBC Four HD, and there is one non-HD channel, Film4+1, on Com 3.
It would be useful to know if your problem is truly related to recording HD, or perhaps related to your reception of Com 3 as Visionman surmises, and a test recording attempt on each of these three channels may help to clarify that.
Roy - Watching BBC1 HD is OK.
When it fails to record, it just doesn't record them. I select the programme for recording, it appears in the list in MyView, Scheduled, but nothing happens. It stays on the list. I tried recording the same program in HD and SD and the SD one worked and the HD one didn't.
I have run the 4G checker and at80 are sending me a filter to se if this solves the problem (I am not convinced!!). BTW I forgot that when we moved the digital the loft aerial was replaced by an external aerial
OH DEAR!!! As I write, just tested recording from BBC1 HD and it is recording it OK!!! Signal strength is 55%, quality is 100% (the same as before).
Can someone tell me what are "normal" strength/quality readings and how these might be improved? The aerial was professionally installed and I watched them check the signal strength at the time.
So, it is an intermittent problem.

Judging by your first message, it appears you're receiving from 3 transmitters, Sandy Heath (Beds), Waltham (East Mids) and Belmont (Lincs).
Check to see if you have any channels lurking in the 800s, and see if BBC1 HD is in there, and if it is recordable.
Unfortunately, it's not possible to perform a manual tune with a YouView box. However, as you say that Sandy Heath gives a considerably stronger signal than the others, you could buy a variable attenuator and adjust it to only receive the strongest signal (ITV Anglia HD) then perform a retune.
This will ensure that only Sandy Heath transmitter will be received by your YouView box.
YouView boxes get upset when they receive from more than 1 transmitter.
After a retune, the variable attenuator can be removed.
Hope this helps,
Chris.
55% Signal strength is great for most receivers (Especially when quality is 100%). But the youview boxes require a strong signal. I added a booster to mine. 65% should be ok but you'll have to make sure it doesn't over power your other channels.
Having said that the program was recording (The Housing Enforcers 0915-1000), it was. BUT IT DIDN'T STOP. When I checked at 1045, it was still recording.
I started watching, then fast forwarded to the end of that programme and found it had also recorded Homes Under the Hammer (scheduled 1000-1100). I then fast forwarded to the end of the recording. I got the "End of Recording" message and when I clicked OK, found that it has stopped recording.
Perhaps the box is not receiving or mis-reading start/stop signals?
Starting another test at 1100
Did you read my post from this morning? You don't seem to have made any comments about it.
Chris.
Can you explain what a "variable attenuator" is, what is does, where I would get one, how much should I expect to pay and how I would use it to receive only the Sandy Heath signal? And what does ITV Anglia HD have to do with it?
Al, it does indeed look like all the aerials elements are the same length. This may not be "so hot" but there is nothing I can do about it. It's a shared aerial provided by the landlord. The aerial is fitted with a booster and I realised that I said it was loft aerial when it is external pole mounted. The booster is in the loft where it is dry and power is available
Should I consider fitting a second booster on my aerial outlet?
Here's a link to variable attenuators
https://www.google.co.uk/search?q=variable+attenuator+tv&espvd=2&biw=1366&bih=643&so...
It the link doesn't work, just Google "variable attenuator"
They are not very expensive. You place it between the aerial lead plug and the YouView box. Adjust it so that you only receive from the strongest transmitter (in your case, Sandy Heath). Then perform a retune.
The reason I said ITV HD Anglia, is because your required BBC1 HD is on the same multiplex (MUX) as ITV HD Anglia (UHF channel 21).
I have to disagree with one of the replies you've received - A wideband aerial will have different size elements. A single band aerial will tend to have similar size elements.
Best regards,
Chris.
It belongs to the landlord, was only installed at the time of the digital switch over and sits about 10 feet above the top of my living room window and I live on the second floor! So I have to work with what I have.
YouView boxes do not do well when torn between two competing transmitters; to be torn between three is a first magnitude clusterfix.
Equalled only by the way your landlord has been taken in by the aerial installer who fitted a non-directional aerial in an area crying out for a narrowly focussed one.
As an exercise, since you can see your aerial on the roof, go outside and see how it compares, both in terms of its elements and its direction, with your neighbours' aerials.
My plan of action is to fit the filter which at800 are sending me.
If that doesn't solve the problem, then I'll get hold of variable attenuator and try that.
I am going on holiday shortly and will set up the YouView box to record while I am away, recording from BBC1SD rather than HD for the duration. I also have a Humax 9200 recorder so I can split recording across both boxes.
Given that I have only a 32" TV, HD is not essential to me. I hardly notice the difference. It's just frustrating when something doesn't record and I have to fall back to iPlayer and it's clones (can't skip through the adverts!).
It's quite well known that channel 21 is at a frequency that can often come in at lower power than the others (on yagis) and as the youview likes strong signals and as your other channels appear ok then I doubt the variable attenuator will fix your particular issue - but stranger things have happened. Adding one would have the same effect as reducing the gain on the amplifier (Perhaps you could temporarily try that?)
Do you know if your neighbours get a good BBC1HD signal? Can you try your youview at theirs?
If not you could try adding a booster to get 21 to a decent strength. After that your options become (a) Use a non youview pvr and (b) don't record the HD channels.
Is there a way of diagnosing the cause of the failure, e.g. error code somewhere?
Having only SD on these would no great loss.
trophytr5 doesn't have a problem with weak signal on channel 21 (Sandy Heath), therefore further RF amplification is going to be of no help at all. In any case, 100% signal quality is the most important issue. This is more important than signal strength.
The OP's most likely problem is the additional reception of two weaker (unwanted) transmitters (Waltham and Belmont). The idea of using a TEMPORARY variable attenuator, whilst performing a retune, is so that ONLY Sandy Heath signals are received by trophytr5's YouView box. Believe me, I DO KNOW WHAT I'M TALKING ABOUT!
The most likely cause of most PVRs not recording properly (getting confused), is due to the PVR being able to receive from more than one region.
Chris.
A friend has a aerial booster he can lend me, so I'm going to try that - as per als suggestion
Interestingly, tried hiding BBC1 HD (to prevent myself from scheduling programmes that are going to fail) and when I tried to record a program from BBC1 SD, it asked me if I wanted to record the HD version. Seems a little nonsensical. Understandable, but nonsensical!!
