G GUY: See Astra 1H/1KR/1L/1M/2C at 19.2°E - LyngSat for frequencies and channels. You should be able to get anything marked as 'PAL'.

Lisa: Multiplex 2 did move from C30 to C33 on 20 April, because it would have clashed with high-power signals from The Wrekin. The prediction for that multiplex is poor.
Digital UK's postcode checker shows that Sutton Coldfield will be a better option for you, both now and after switchover.

George: Only the BBC A multiplex (replacing Mux 1) and Multiplex A have moved so far. Mux 2 is still on C68 and should still be on C56. However, C56 only transmits at 1.1 kW, nearly 20 dB quieter than the new high-power BBC multiplex, and some boxes might have trouble with that much difference in signal levels.
Some boxes just tune in the first version of the channels that they see, rather than the best quality, so check whether there's another version of ITV1 up in the 800s, or somewhere else in the guide, which would be the version at C68. I'm afraid I don't know which area C56 was intended to cover.
Multiplex A, which was on C48, has moved to C49 already. This is so Woodbridge (permanently), Burnham on Crouch and Clacton (temporarily) can use C48 for BBC A.
At your postcode, Digital UK predict no reliable coverage on Mux 2 at present. I'm not sure if this is a change as they only show today onwards.

Dale: Yes, in this interim period between the first and second stages of switchover, BBC Four and the BBC radio stations are transmitted from both high-power BBC A and low-power Mux B. In two weeks Mux B closes down and is (logically) replaced by the HD multiplex. (The HD multiplex takes over Channel 4's frequency, and Mux B's frequency is released.)
Which version was stored at 9 depends on how your box handles multiple versions; it might be the Mux B version if it just stores the first found, or the BBC A version if it stores the best quality.

Brian: Logik is a Dixons/Currys group brand. I'm afraid they don't seem to be making much information available. Try contacting their customer support at Customer support | Dixons | .

Dave: The irony is that the move to DAB is intended to free up the FM band for more local stations. There is actually nothing else that can reasonably use VHF Band II - the band's entire width is only 20.5 MHz, which is about the same as ONE WiFi channel in a/b/g mode. 802.11n can be configured to use twice the width, 40 MHz.

joe abbott: It's not clear from the manual at TV Re-tune how to do a complete reset of the box, which is often necessary at switchover. On newer equipment, 'Add Channels' does forget the old locations.
My guess would be that you now have too much signal. If you have a booster or other amplifier, try removing it. Or you may need to add an attenuator.

John A.: My mistake, Rouncefall is indeed shown as horizontally-polarized.
The timing of the signals from both transmitters reaching your aerial is critical. Outside the designed coverage area, the signals can conflict rather than help (self-interference). Digital UK's trade predictor shows variable reception whether you point the aerial to Sudbury or to Rouncefall. It only ultimately shows 'good' reception on all multiplexes from Dover.

Mark: Have you retuned your box since April? The 'red button' video stream, channel 301, moved from Multiplex B to Multiplex 1 a couple of months ago.
(I realise it's too late for today's game but that should sort you out for the next round.).
