We just switched over to Direct TV. Our current set up is: Genie in the family room. Mini's in five bedrooms. We are having issues with not enough capacity. Can we add additional HD receivers so everyone can watch at the same time. Our children are all in their twenties and often want to watch different programs in the evening and we cannot record on the DVR. We don't need DVR's in four of the bedrooms just HD receivers. Any suggestions?
