Well I tried several changes last night.
Tried moving the Oppo to the other DVI same problem, turn on the Oppo remote doesn't work, turn it off and it works again.

Hooked up my HD receiver through the other DVI turn that on and same problem, although it does respond a little bit, but might loop, vol down and it suddenly goes way down. Allmost like the "blocking" signal is not quite as strong on that piece.

Disconnected the DVI out from the back of the 990 so just have the 2 DVI in's hooked up. Still same problem.

So I guess there must be something up with my 990 as I seem to be the only one with this issue.

I'll try tech support again and see if the have any other possible solutions.
