Thanks for your input. It confirms that the issue is only with me or at least my area.
I have had at least three engineer visits to sort this out - the last one from a SENIOR engineer (same guy as before) but I am no further forward.
They blamed the fact that THEY used a three way splitter and that this was reducing the signal, so one Virgin box which was free with the deal was removed and a two way splitter used. It made no difference. They changed a short connecting wire - no difference and then did something remotely (they said) - no difference!
They keep saying that the signal is weak in some respect and that this will be sorted - it never is! The channel is unwatchable most of the time!
I am sorry to read that you have experienced some interruptions on that channel. After having a look at the connection and running some tests, it's clear to see that there are some issues that would need to be looked at and adjusted by and engineer, your box is not connecting to the network.
