I too have the irrataion of the unit switching from my selected mode to something else when I pop in a DVD. I know some DVDs have metadata that flags the processor to change modes, but my Sony EP9ES handled this switching much more elegantly. I have found I have to go over to the 950 and punch the button repeatedly to get it into Dobly EX after a DVD has changed it to 2.0 prologic or something. I have to go over to the 950 'cause I use component connections for my projector, and It's a pain to switch over to S-video just to see what mode I'm in.
