How do you change the display settings when going from HDMI to composite? Sometimes I need to switch the PS3 from my HDMI HD set to a SD set in the other room for the kids. When I try to do it, I go to the display settings switch it to composite the screen goes blank for around 30 seconds and come back on with HDMI settings. I could switch it before the newer system updates but now there seems to be a problem. Thanks for anyones help!!!!
