I have connected my new Panasonic plasma and Panasonic home theater sys as well as the TW set top box up to the revue. While the revue works with everything, it will NOT control the volume or off/on on the TV??? I've tried directly mapping/assigning the keys with the remote several times. The Revue will control everything but the TV. A bit frustrating! I have the TV connected via HDMI ARC cable (3d plasma) to the home theater system and the TV is also connected connected via standard HDMI to the Revue box. With the current config, I can run/control everything, home theater, set top box and even the TV channels. Just no volume control with the TV or power functions. Not even with mapping the keys with the TV's remote. The theater system only has one HDMI connection and it requires it to be connected via HDMI ARC cable to the TV> Any ideas???
