Hiya,
I forgot to mention that it has all been sorted now. The guy that came out, was fantastic - he gave me a VM dongle and sorted out the downstream power issues.
Aswell, the guys that installed me put a V box in and due to the sales rep mess up, I spoke to customer services who sent me a V+ Free of charge.
Aswell, I wantd a multi room option and as a gesture of goodwill I got a second box installed for free and only £5 a month.
I must say, I am very very very very impressed with VM and their service. I am looving the sexy V+ Box.
Virgin and the team, you have done a fantastic job
