Recently being having a problem with my PS3 in that the settings seem to get reset. This mainly looks like the display / sound settings. When I turn the PS3 on, instead of being displayed in 1080p format, it seems to be in large format, and says that it has found a HDMI connection, and would you like to output video and sound through this .. so I say Yes, and set it all back up. It then works for a couple of days, and then when I switch it on again, get the same message as if the settings have been reset. This is connected to a panasonic 42" plasma via HDMI and to an Amp via optical. The only other thing, is that I do have an HDMI Splitter, but this is of the auto-sensing style. Help !!
