Gonk I may be wrong but from what I understand a A/V processor needs to be able to handle HDMI 1.4 in order to pass 3D I didn't think the 990 could do that (didn't buy the C8000 for 3D but since it's included I might as well play with it).

Didn't really figure any main stream manufacturer's BR would have a good analog section but maybe technology allows for this so will give it a try. Is there a 5.1 wiring harness available for this?

I had to go check if I had any speakers set to small since all mine are rather large but apparently when I set this up a couple of years ago I chose all small plus subwoofer. I'll read your setup guide for the 83/990.

I emailed Oppo a couple of weeks ago asking if any of their BR's could be updated to 3D and he said they were looking into that but it didn't look promising, I only asked because Sony BR's and PS3 can be upgraded to 3D via firmware. Since I got the 6900 for free I might still get the Oppo 83 sometime unless it's getting a little dated, or Oppo comes out with something comparable.
