I thought it was just me......but, I'm having the same problem....the audio is lagging BEHIND the video......and, as far as I can tell, distance settings done with the automatic set up are spot on. And, even if they were a little off, I can't imagine them making that much of a difference. Plus, I am unable to use the front panel display.....it just doesn't respond to the remote command. So, I have to toggle to the OSD and back.....making it much more difficult....and just like Steve said...all it does is make it worse anyway. I kind of gave up on it.....other than this issue, the 990 is super.
