Does anyone know how to completely reset a 565? Mine had taken to ignoring my setting of two surrounds and asking for the size of "sides" and "rear" speakers. I know from past, painful, experience that it will not work well with analog sides but it insists on requesting their size. I think if I could completely reset it I could get it working.

The way it is now all I can get is noise from the speakers. Needless to say, this is very frustrating.

565 6.0 Z3, 562V, DSP5000C, 4x DSP5000.
