Questions about shutting off NSZ-GT1? Is it a good idea to shut off the Sony when not using? There is a button on remote to shut off-turns on/off button red. Also looked at settings for auto shut off. Saw one setting where you have the option for power saving option and also there auto shut off. I hit option for quick start and auto off after 2 hours of non use. I noticed in the AM the button stayed green. I also saw another auto shut off under HDMI setting somewhere-it said auto off. I left that alone. So if I should shut down and I have connected HDMI-how should I set auto shut down? Am I better off turning off from remote? Does the Red light go on after auto shut off? Advice appreciated, thanks.
