I posted in the Co-Star forum but I am hoping to reach a wider audience. I have a Vizio Co-Star and a Vizio LED TV with HDMI CEC enabled on both. The TV has a setup utility to tell you if it sees the Co-Star and it did find it, listing it on the screen (not sure if the Co-Star has a similar test for HDMI CEC functionality?). I was hoping to be able to turn on/off the Co-Star whenever I point the Vizio TV's IR remote at the TV and turn it off. If I could accomplish that, it doesn't seem like a great leap for the xfinity HD-STB remote to turn off all devices; HD-STB, TV and by extension the Co-Star. I am curious to know if anyone using any of the Google TV STBs have been able to control both TV and GTV STB using HDMI CEC?
