Why is my TV flickering, displaying distorted colors, or not able to get video and audio on both TVs?

Certain Cable/FiOS Set-top boxes and DVR boxes are limited to only 1 downstream HDCP (high-bandwidth digital content protection) device that they can connect to. This means that devices like MyWirelessTV, A/V Receiver, Google TV, and HDMI repeaters/switches that are strictly adhering to the HDCP requirements cannot legally pass video to the display. You can call your Service Provider and describe the "HDMI repeater/switch" related issue, and request a free firmware update. Or As an alternative, you could also request that the Service Provider replace the HD Cable or FiOS STB/DVR box, with a model that can support repeater mode.
