General note - if you are retuning you must do a "first time installation" or do this - My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice . An "add channels" will only confuse your receiver.

Brian, out of interest, why is MUX B not turned off at the first retune date, given that the new PSB1 mux carries everything that was on MUX B? MUX B is now just a subset of PSB1 that doesn't need to be there.
Cheers,
Adam.

Adam B: Because anyone who hasn't retuned will no longer get the channels on it, which includes the two "hidden" Sky Sports channels.

I have a problem I'm hoping someone can help with.
My house has 5 TVs; kitchen, living room, bedrooms 1-3. The living room and bedrooms 1+3 receive all muxes fine, no problems at all. Signal strength is a little poor on 2 and A-D but I guess that is expected before the 13th. The other two rooms however, only receive 1 and B. Nothing at all in the 40s range.
I have tried various combinations of TVs and set top boxes in all the rooms, and the result is the same regardless of the equipment. The only difference in the rooms as far as I can make out is the length of RF cable between the aerial/booster-splitter and the wall sockets. The rooms are experiencing the problem have roughly double the length of RF.
Would the cable length be responsible for the problem? Do the cables wear over time? They were all put in approx 25 years ago when the house was built.
Any help would be appreciated, thanks.

Sterart,
No. The first 4 Freeview HD channels start on the 15th April at DSO stage 2. You will receive BBC1 HD, BBC HD, ITV1 HD & CH4 HD. I get Freeview SD and Freesat HD & SD so i'm looking forward to CH4 HD coming to Freesat in April. I would guess that the Freesat HD pictures will be slightly better than Freeview HD ones.

Thanks Martini,
I have been looking all over the place for information about HD availability, but was unable to find any.
Oh well, just a bit longer to wait...

Loft antenna in Newmarket (29m ASL) is working fine. Bought a 52 element wideband plus a £20 gigibox for the main TV a couple of weeks ago and it is adequate on all channels. Bedroom TV on old loft mounted Group A gives a slightly noisy signal on Analogue but the BBCA mux is good.
