5 Roommates Using Live TV at the same time

I have 4 roommates each had a cox mini box and I have a conture 1 box. Everything was fine until we upgraded 4 of the mini boxes to the New conture 2. Now when all of them are home the boxes wont let all 5 of us watch live tv at the same time. We get a notification on the screen which says (turn off unused non DVR box to watch live tv) In short some one gets knocked off of live TV and gets this notice.
