Do you have an example of something that does these slow pans (other than pink noise?) I am curious. I have a VP100 and M80s... probably not a great match. The only time I notice an issue is with live broadcasts (auto racing) where they mysteriously place the commentator's voice on the left front for a second instead of the center. It's probably the decoding I'm using, though.

I am the Doctor, and THIS... is my SPOON!
