Mike Tucker: Does the TV have an in-built "booster" which can be turned on for reception of this channel?

Mike: If you've got an aerial amplifier then any filter will need to go before it.

KC: You have overcome it by manually tuning!
I presume your question about "plans" relates to the automatic tuning sequence. How could it possibly be overcome??!!

Mike Tucker: If you have an aerial in the days of four-channel analogue then it might be a Group C/D one and therefore C33 is out-of-group for your aerial.
See:
Aerials, TV Aerial and Digital Aerial
Basically, Group C/D is the top third of the band of TV frequencies (UHF channels) and such an aerial is most sensitive on those frequencies. (You may have had your C/D aerial replaced to pick up analogue Channel 5 on C37.)
Also, try a manual scan of UHF channel 31, which is COM7 from Wenvoe.

Keith Parry: See the list of services from Digital UK:
Digital UK Industry - Channel listings
True Entertainment is not available from transmitters in Wales. This is because Channel 4 and S4C are carried on PSB2 multiplex (the rest of the UK only has Channel 4). In Wales E4 goes in place of True Entertainment (on COM4) because it isn't on PSB2 (owing to S4C being there).
Try a manual scan of UHF channel 48 which is Mendip's COM4.

kenneth okane: Firstly, confirm that your TV is actually tuned to Black Hill for all channels and not Darvel (for some). Do this by viewing the signal strength screen on each of the following and checking the tuned UHF channel number (or frequency in MHz):
BBC One | Black Hill=C46 | Darvel=C22
STV | Black Hill=C43 | Darvel=C25
BBC One HD (if applicable) | Black Hill=C40
ITV3 | Black Hill=C41 | Darvel=C23
Pick | Black Hill=C44 | Darvel=C26
4music | Black Hill=C47 | Darvel=C29
If it only gives a readout in MHz then these values are given at the top of this page and at the top of that for Darvel.
If it turns out that one or more are tuned to Darvel then run the automatic tuning scan through with the aerial unplugged until 30%.
If it is tuned to Black Hill then as you appear to be using a communal aerial system it would appear that the problem might be with it, so it might be worth checking with neighbours to see if their reception is also affected.

KC: I believe that this is addressed with the latest DVB-T2 (Freeview HD) devices. I don't have a copy, but it's been discussed on here a while back about the "D Book" which carries requirements for Freeview equipment:
DTG :: The D-Book
One such requirement is, on completion of the automatic tuning scan, for the user to be presented with a choice of region/network in cases where more than one has been picked up. Does your receiver not have such a preference, either presented on completion of the scan or buried in the menu?

MikeB, kenneth okane: As the aerial system appears to be a communal one then the exact reason is largely immaterial as in such circumstances Kenneth needs to report the fault to the party responsible for it in order to achieve rectification.

SomeGuyFromBristol: I would suggest that Mendip could be generally the preferred transmitter for your area. The aerials adjacent to the shops are certainly pointing there, so tune to C51 for LBS.

Mike Tucker: Are you sure that COM7 was previously being received from Mendip and not another transmitter? (Not knowing your location it is impossible to get an idea as to whether this might be a possibility.).
