ok guys, here's the deal,

I have 5 bedrooms, a loft, and a family room that currently have cable with HD programming.  At times I have family over and 5 people watch 5 different shows.  I sought info from the wiki and forum posts and have read many different things, conflicting many times.  What i want to do is build my MD's with cards that will enable me to use the cable i currently use, until i get HD satellite without having to change or add additional cards. I want to be able to hook both the cable and satellite up and use them interchangeably.  I looked at the hdhomerun, but it does not support satellite. Can someone please tell what i need to purchase??
