i think it depends on how many URB's u have in london! some parts of notts still had all the channles 5 weeks after the new cards were sent out ...but now were all black & gone of totaly .......get v+ing lol ,
I assume you are on the M TV package as part of a bundle.
Nobody is forcing you to use the new card and VM box but at least you will be able to recieve basic services with it. I know plenty of people who have the 'free' base TV package but don't use it because they have sky, virgin don't seem to care.
