Nick: I don't think there are any channels that are not in the EPG already, ITV4+1 aside. You can look though the list here if you want Eurobird 1 & Astra 2A/2B/2D at 28.2°E - LyngSat .
The Sky box deletes the "more channels" if you start the box without a subscription card in the slot.

Nick: You can find lists of free-to-air satellite services at Eurobird 1 & Astra 2A/2B/2D at 28.2°E - LyngSat and at Astra 2A / Astra 2B / Astra 2D / Eurobird 1 (28.2°E) - All transmissions - frequencies - KingOfSat .
As for why the box only retains the extra channels for a few days, no idea. Perhaps the box needs to remain powered?

Thank you both. I have a 'free' card in there but it is out of date. Even when it was not, the box 'forgot' the extra channels. It is plugged in all the time.

Dear Brian,
When you watch analogue tv on an old 4 x 3 tv you have a thin black line top and bottom. This is quite acceptable. If you play Sky or freeview through the tv, despite having a choice of picture shapes, you cannot get the same shape picture. If you want to see the whole picture, you have to settle for a thick black line top and bottom. Why is this?
Thanks,
Nick.

Nick: Most, but not all, Freeview boxes offer the 14:9 option, which is what you see on analogue TV.
However, some boxes only offer "centre cut out" 4:3 and the "thin letterbox" 16:9 options.

Many thanks Brian.
Is Sky different? I have a 14x9 and two 4x3 settings.
One 4x3 makes the pic too big so I lose the sides and the other gets the whole pic in but with a thick line top and bottom. Do they deliberately make it that we cannot see the free channels on Sky properly on an old tv? I assume there is nothing I can do on an old set to see Sky the same shape and size as the anaalogue pic. Thanks.

Thanks Brian.
I don't suppose you know of any flat tvs that you can plug speakers into as opposed to amp plus speakers?
Sound on most is not particularly good. It is all very well for them to claim they use less power than crt tvs----not if you then have to use an amp to get the decent sound you got on a big box tv, not to mention the cost of the amp.
Many thanks.
Nick

Nick: You can buy "computer speakers" which attach to the headphone output of the set, where the amplifier is built into the speakers, or sometimes the bass cabinet. I have used a set of Creative Labs speakers on a TV with awful sound a while ago.

Dear Brian,
Thanks for the answer about computer speakers. I would guess that even they are not particularly good though. I have many good speakers but if they need an amp, then that puts up the power consumption of these so called economical flat screens. Apart from that, I have to get up every time I want to adjust the volume! Great pity they don't put conventional extension speaker sockets on these new tvs. Some of the old sets had good sound with their satellite speakers.
A while back I asked what might be causing the Herringbone on analogue Sudbury BBC 1. You suggested it might be Bluebell Hill, but I see that tx does not use channel 51. Have you other ideas?
Best wishes,
Nick.
