I don't think anything is wired wrong. I have the exact same issue, it's just that I so rarely turn off the TV when audio is playing that this has never bothered me like it does Mark.

Chris - how do you tell you your Pio plasma to turn off the display without turning off the TV? I have a Pio plasma as well so am very curious.
