I've also had problems with a Sony VTX-D800U freeview box as reported by Dave Kimber, where (after retuning) BBC2 keeps switching to BBC1 after a few seconds.
Following Dave's advice, the problem went away after a mains power cycle.

Re-tuned television, freeview box, strong BBC 1 & 2, no ITV, Channel 4 or 5. Freeview box is a Wharfdale TU160DTR, television is Samsung LE40R73BD.
We have previously received ITV & channels 4 & 5 although not good signals.

Menna: check for a loose, disconnected or broken cable, because you should be getting perfect reception. Also, if you retuned before 6am on Wednesday, retune again - all services were off-air at that time.
If you didn't retune at all on Wednesday, you would have lost BBC channels but should still have all the others.
Some boxes auto-retune every night and could have been confused when the services were off air.

David Brient: if there's a time of day that you've noticed that ITV, C4 and C5 were normally working, try retuning it then. Or try a manual update of channels on C45.
You are predicted to have variable reception of these channels at the moment. No problems are shown once switchover completes on the 13th (10 days time).

Thanks very much to Dave Kimber - I was having similar problems with the Sony DTX-V800U box. BBC2 would switch to black a few seconds after closing the EPG (but fine all the time the EPG was visible) - even after a full re-tune.
Power cycling the box completely seems to have cleared the problem!

I am in the Cambridgeshire and feed off the Sandy Heath transmitter. When I did a rescan on the 30th. I was left with three selections as follows:
Cambridge and Beds. 18 services
Cambridge and Beds. 21 services
Midlands. 18 services
I know that I can ignore the Midlands(Waltham) but which of the other two should I select, I can only select one.

John: I would select Cambridge and Beds 21 services. I am guessing this is Mux BBCA and the others are MuxB options as you dont say which,if any, other muxes were found and channels stored straight away.

John: When the broadcasters make changes to the transmitters, they often add a dot to the end of the region name, so they know that a change has gone through. You probably have one with a dot and one without. I believe the boxes are supposed to ignore this, but not all do.
It also ought to be possible to select top preference and second preference, in case you actually want services from two regions, but again, not all boxes allow this.
What make and model of box do you have? It's worth checking to see if there's been an update that you've missed - particularly if this is a new box but could have been sitting in the shop or warehouse for a while.
The 21 services region is likely to be the BBC A multiplex, while 18 services is likely to be the low power Multiplex B - all services on Mux B are also on BBC A for the next 10 days, except for Sky Sports 1 and 2. On the 13th, Multiplex B closes for good (at Sandy Heath) and is replaced by the HD multiplex.
It may simply be that the box is telling you it's found three different versions of BBC Four, CBeebies, Red Button and the BBC radio stations.
My understanding is that it should also have listed the ITV channels if your signal quality is good enough to receive those. The prediction looks reasonably good - have you had Freeview before? Are you using an outdoor, roof-mounted aerial, or a loft aerial?

In Wellingborough, we have lost at least BBC1, 2, 3, News. We have updated the box several times. Sometimes the box does not recognise these channels; sometimes they are there but have rubbish reception. Others seem OK.
Digital aerial is on the roof.

Similar Problems down the Nene valley in Irthlngborough, had to do a manual tune on Channel 27 to get it to work on one TV, other worked, but both show very high signal, expect problems is too strong a signal.
If you have an aerial amplifier try turning the gain down or fitting an antenuator.
Unfortunately I also have opposite problem on Channel 67, the signal is barely there, all beit at half decent quality, don't expect much luck when it qoes to 64QAM next week.
