I keep having a problem with my box. I turn the power off and hit the menu button to get into the setup. I select 720p, hit the menu to exit out, turn the box back on, and everything works great. For a while. At some point all the settings get reverted to default, and I have to go back in and select 720p again.
I have a pretty simple setup. HDMI out from the box, into an Onkyo 606, and then into the TV.
Has anyone had this occur? If so, how do you fix it?
