Gooomz,
My outlaw gear hasn't been delivered yet, but I've been reading the 990 manual online in preparation. Your problem sounds like it could be an input assignment. I assume you were using a different audio input with your DVD player prior to buying the BD player. Now the DVD player needs to have 7.1 analog assigned as the audio input. It probably has a digital audio input assigned now. Just a guess on my part, but maybe this will help you find the problem.
Regards,
Bill
