My Denon AVR-2309ci keeps going "out of sync" 7ch vs Dolby

[jc480]

Couple issues...when everything is working fine, I'm in heaven.

The problems I'm having are...

My BD player...if I stop it and leave it stopped overnight and resume, I lose sound....basically I have to power everything down, unplug the BD player and re-power everything up. This may be a Java issue with the BD player and not the receiver....maybe....

My TV tuner box...I have to turn everything on in this order...

Denon
TV box (it has to be NON POWERED not just off)

I get Dolby 5.1 surround - the way it should be

If I watch a BD movie and then switch over to the TV, it's 7ch stereo...if I don't powerup everything from a non-powered starting point IN THE CORRECT ORDER (Receiver FIRST) then receiver goes to 7ch stereo and NOT, as it should be, the Dolby 5.1

Really confused why this is happening. Why doesn't it automatically go to the right sound mode instead of having to send it a "fresh" signal from a newly powered source. It's like it needs to "clear" the signal and get something fresh, otherwise it goes to the crappy 7ch sound.

Confused.
