Yep, got the broadband hub delivered with the kit. (I switching from tivo with no broadband to V6 with broadband).
I think it was the virgin self-install video that confused me - as it shows a New isolator cable as being supplied ("use the black band end" etc. My current isolator cable is so old, it has no 'black band').
It's not an isolator cable you've got, just an old fashioned coaxial cable connected to the isolator. As advised the V6 is just a straight swap for the TiVo and all you need do is to connect the V6 to the hub (best done with an Ethernet cable).
Basically, from what I've been told, I currently I have a coax cable, which connects the internal wall socket (mines labelled 'telewest" but apart from that the socket looks the same as the virgin one) directly to the tivo box. From what I've been told, if I've understood correctly, that thankfully, this coax cable can be used with the V6 (i.e. connect the coax cable to the splitter and then link everything up).
What confused me, is that virgin both in its paper Installation Guide, and in its 'Installing your V6' video specifically mention the "isolator cable", and shows it being supplied. Would be interested to know what this is? And how, if any, the coax cable and isolator cable differ? And in what different scenarios they are used?
But really, I'm just glad that it looks like I can set up the new V6 tomorrow morning with no issues.
