This may seem like a silly question but..
I am getting Ntl tv installed in my room, and I already have a Broadband connection through an ntl box on my wall.. I use aol as my ISP not ntl. When the engineer comes to install the TV package 1.. will he use this point, or install another one? 2.. do I need a normal TV aerial point in my room, as I don't have one

or is it all done through that one cable?
thanks, jess
