This gets even weirder. At least to me.

With cable, receiver and tv on, just switching off the tv, then on again, will cause the cable box setting to default back to HDMI. I have to go back into the settings of the cable box and reset for digital. Turning off just cable box, changes nothing.

This makes no sense to me.
