Op seems incapable of answering a simple question.
Without more info. Here is my theory (pure guesswork)
1 I guess the aerial on Lark Stoke is correctly vertically polarised and aligned on Lark Stoke. On a auto tune it finds BBC1 West Mids on Channel 32.
Next it finds another mux on UHF channel 32 off the back of the aerial. Gets stored at 800 plus. Most likely from the main power transmitter at Mendip (horizontally polarised) and a much higher power than Lark Stoke.
If speculation is correct manual tune will never work. The aerial will need to be rotated to horizontal and re-aligned on Mendip to reject the channel 32 Mux from Lark Stoke.
I guess the TV has the same issues but the OP has found the duplicate channel UHF 32 mux ( If he posted the channel number (lcn) it would confirm this).
I guess the TV will also have BBC1-West Mids on on it's correct LCN.
A simple test will confirm all the Op has to do is watch the South West programme and identify the UHF Mux channel it is using.
Unless the OP answered our questions, it's all pure speculation.
As we all know trying to use Accurate recording with channels from more than 1 transmitter causes all sorts of recording issues.
Unless the OP gives us more info. What more can we do ?????
