Jon D - Sounds like your scan put weak channels it came to first in the 1 2 3 slots and stored stronger ones in an overflow area. You can probably move them; or try retuning with the aerial unplugged until you get past the ones you don't want.

Jon D: As a test to see what transmitters you could be picking up in your area, I put the postcode for Cineworld in Stevenage into the Digital UK Tradeview predictor:
Postcode Checker - Trade View
As I suspected, Crystal Palace may be coming in strong in your area now that it has switched over (which it did so on Wednesday).
Confirm where the erroneous BBC One and ITV1 channels are coming from. Do this by going to them and bringing up the signal strength screen. Most receivers give the UHF channel number (equivalent to frequency) that it is tuned to. If BBC One is on C23 and ITV1 on C26 then those signals are coming from Crystal Palace. You then know what you're trying to avoid when the device goes through its scan.
Unfortunately the signals from Crystal Palace are all in the 20s, as are the Public Service channels from Sandy Heath. The Commercial channels (ITV3, Pick TV, Yesterday etc) from Sandy are in the 40s and 50s (except for one which I changes on 9th May and for which you will have to retune for).
Refer to "After switchover configuration" on this page Freeview multiplexes | ukfree.tv - independent free digital TV advice
The programme channels are broadcast in groups known as multiplexes.
Now, what I would do in your situation, if it turns out that the erroneous BBC and ITV signals are from Crystal Palace is to run the automatic tuning scan with the aerial lead unplugged up until 50%. This should give you ArqA (Pick TV etc) and ArqB (Yesterday) which are on 52 and 48 respectively. When you do this after 9th May it will also give you SDN (ITV3) which will then be on 51.
Having done this, then go to manual tune (if your receiver has this function) and manually add the missing multiplexes. BBC A (BBC One etc) is on C27 and D3&4 (ITV1 etc) is on C24. If the receiver has HD, then you need to manually tune to C21 for HD channels.
Finally, as SDN is presently on C31, manually add it. This will move to C51 on 9th May.
If this is a suitable workaround, then make a note of it should you need to retune at a later date.

Jon D - there's a note about temp aerials above. Dunno personally.
You can probably move the channels you want into the 1 2 3 etc. slots.
