My cable company, Adelphia, tells me I must use their box if I order digital cable, period. I told them that the TV I am getting is a digital TV and they appeared confused, then re-affirmed that I would need to use their box. Do I? The TV I ordered is the Mits WS65807 HD-Ready. I would like to avoid another box, and another remote, and all the BS that goes with those things. Can I ? Are the folks at Adelphia wrong as I suspect?
