I'm a current Triple Play subscriber in Philadelphia. I'd like to obtain the X1 platform. I have the anyroom DVR in my living room and three other cable boxes throughout the house. I'd like to know whether I will incur any additional costs if I upgrade to the X1 platform. I was told that each new X1 box would cost $17.95 per month, which is a significant increase over the $9.95 per month I pay for the current boxes.
