Half the stuff you have said isn't really VMs fault though.
Broadband :
Routers are your gig, not VM's, they provide you with the modem, you can do what you like with the connection.
You don't need to use the software CD, you can install it just like a standard ethernet connection.
TV:
They provide you with TV, if you chosoe to attach other stuff again you can't expect them to connect all that up for you.
Its not up to Virgin to provide you with the cable or access to routing TV to two screens, thats why they sell multi-room boxes.
Its a good blog, but you gotta be careful with some of the things, likewise I had issues with the state they left the install in etc etc and time was an issue - but don't knock them for using their kit outside the scope
There are issues with installs, I know this, I taught the guy how to connect my V+ box up using HDMI only the other week.
