I just did some wire adjustments on my system to accommodate a new PVR and discovered my network adapter in the 3808 was locked up. I had to do hard reset on the system to get everything working again. This means I lost all my settings etc. as I hadn't done a back up of my system settings, so I needed to run through Audyssey once again. I discovered I had managed to reverse the LF speaker connection, Audyssey revealed it to me while doing the setup, it is kind of nice it looks for these things.
