KYpride,
Are you saying that you are only having problems when watching/listening to a DVD, not when watching TV?
If that is the case, I think it is a setup problem, not some type of a resonance issue. How do you have your TV sound and DVD sound connected to the receiver? Are you using L&R analog RCA interconnect cables or are you using a coax or optical digital cable?
