S.P.
Comcast.
My husband works for comcast so it is dirt cheap for me!
But honeslty I have had zero issues with cable/phone/internet all on the same network. They only time it doesn't work is when the power has gone out. I have never lost cable service, and not because my husband works there, he's not very responsive to us if there is an issue because he has thousands of "customers" to worry about first! DVR is awesome, some plans let you have DVR on multiple boxes that can DVR seperate programs at the same time!
