3 genie minis in 1 room - DirecTV DVR

For DirecTV TV services which include DVRs and receivers, 3 genie minis in 1 room I have 3 genie minis that get setup in one room and it seems that whenever I run all 3 at once that the TVs constantly freeze up and skip. This never happened before upgrading to all genie minis. Would you be able to help me figure this out.
