Have you had high winds recently? The weakest channels on our box all suddenly improved after a storm, but that was soon followed by the main channels (BBC etc) beginning to deteriorate in bad weather. The reason for it all was the dish had moved.
A well-aimed dish picks out the best compromise point in between all the satellites broadcasting to the UK. But because the dish can't be aimed precisely at all of the sats simultaneously, some will always be better or worse than others. Many people will not be any the wiser, but if you have interference from trees, poor cabling or connectors, or are towards the edge of the sat footprints (in Scotland, for example), then you will notice that some of the channels, the ones broadcast from the sats you are not so well aimed at, will suffer.
I would say it's unlikely that the transmit power of any of the channels has changed. If the quality shift was sudden, then they may have moved to a different satellite or (in my experience more likely) your dish has shifted position slightly.
