My old AV9000 always did the same thing - I'm pretty sure it's an oversight in its design. I kept the main settings written down on a piece of paper on the end table next to the couch so that I could fairly quickly re-set the configuration.
That's one of the main reasons that I'm now using the AV8003 (although I was mighty glad that I still had the AV9000 when the new unit developed a problem that required a lengthy visit to the factory for repair).
