We recently experienced reception problems which turned out to be down to weather damage to the dish/receiver. (Couldn't retune, didn't even recognise our postcode!) Aerial specialist replaced faulty part and tested with good strength signal shown. (As aerial was twelve years old and faces prevailing weather, not too surprising!)
However, since then, we have been unable to set recorder to record two programmes simultaneously, or sometimes even watch some of the other TV channels, whilst one is recording. We are limited to certain, apparently random, TV Channels that we can switch to, which are highlighted on the Channel Listings in black.
Our default BBC channel is BBC SE, but occasionally, having set one programme to record, when trying set something on BBC SE to record at the same time, we get the message "this channel is not available", but BBC South might be an alternative (although there is no consistency in this and nothing else might be available at all).
I am fairly convinced it is a problem with the aerial, but the engineer says not.
Anyone got any ideas (not in technical jargon please, I don't understand electronics!).
