John: basically it looks like ITV have only invested in enough delay boxes to manage the six satellite services, rather than all 12 traditional regional licences that they own (and the micro-regions that make up those larger regions). All the transmitters in Wales, the West and South-West (former Westcountry region) are transmitting the Wales +1 service.

ITV are really more concerned with ensuring that the right adverts are played out: it's possible to buy space on all of Wales, the West and South-West as a single macro region.

I live in Chippenham and up until recently had no problems with the Mendip transmitter. However I recently noticed that 4Music channel (18) was missing so I did a re-scan and saved all channels again. This works fine until I turn the TV off when it is missing again. (Philips 37PFL5522D)
When I checked your data above I notice that all the programs transmitted on Arqiva B are missing. Re-scan gets them back until I turn the TV off when they all fail again.
I have checked antenna and connections and all seem fine, besides I receive all these programs on the Hard Disc Recorder on the same antenna okay and two other TV/digiboxes on other older antennas.
Could this be a problem with TV not storing channels correctly?

Philips 5522 series of televisions, LC7.2E chassis have a softwarwe fault on Arqiva B, channel 67 off Mendip. Tuning doesn't stay. Philips don't appear to know what to do about it and it may resolve itself in September but don't hold your breath!

I bought a Panasonic TX-L42D25B television in August 2010. The EPG worked fine until about three months ago when much of it was blank on both Freeview and Freesat. About three weeks ago there was a software update and the EPG was then fine. But a week ago I went on holiday and I returned to find it is again as bad as ever (THere had not been anoither software update in that time)

Both times the problem occurred I did a complete retune as well as a return to shipping condition - it did not help.

I have a roof aerial and all other equipment (Including an earlier Panasonic TV and DVD HD)work fine. The signal strength and quality on the set are showing as fine.
When it first went wrong Panasonic said it was a problem with the Mendip Transmitter (I live in Paulton near Midsomer Norton)which affects TV sets made in 2010. Can that be right? And would that also affect the EPG on Freesat?

I have emailed Panasonic 3 times but cannot get any reply

I'm trying to manually tune my Panasonic recorder (EX768) into channel 67 in order to regain the Arquiva B stations that used to be on 59. When I scan for them, all channels come up with 10 for both signal quality and strength, but after I press EXIT (as directed in the handbook) none of the stations are saved.

(This manual tuning process worked fine after the analogue switch-off - when it was necessary because the auto-tune saves only Stockland Hill channels, not Mendip, with loads of interference.)

I've tried disconnecting everything except the Scart lead for the (analogue) TV. I'm reluctant to do a complete re-tune again, in case I'm unable to save even PSB channels after I've cleared them. I have no other digital receivers to compare.

Any other suggestions, please?

Curiously, my DVR is Panasonic, bought 2010, and I live in Midsomer Norton - all similar to Andre Fournier above.

Panasonic equipment tend to be a bit keen to come up with a "new signal found" message and ask for a retune (unless you turn the message off).
I've seen Panasonic kit also baulk at a signal that it regard as "too strong" and then decide to choose the signals from a distant relay Tx.
I'd suggest a signal attenuator for your aerial lead - just for retuning purposed (so the box or TV can't see the weak signal and the strong signal isn't too "bright" for it. Probably need as much as 18dB, maybe more.
