I have tried that, and every other thing I could think of. I went back through the manual and can't figure it out. On my old Denod it would channge surround parameters. I was hoping someone might have an idea before I reset it.Is it possible it changed inputs? If all else fails go through setup menu again . Good luck
I think a reset is probably your best option. You saved your last good config file with the web interface, right??
If not, it's a good habit to get in to.
