Thank you AVFan,

I will look into the cable box as one of the problems, we have switched the comcast box many times due to its poor quality.
The set up for the speakers and tv are:
TV HDMI to DVI out (audio & video); cable HDMI to DVI 1 ; cable audio to coaxial 1 ; DVD HDMI to DVI 2 ; DVD Audio to Coaxial 2. This is how I currently have the system connected. I hope this will help any Gunslingers out their that might have some ideas.

Thank you,

Craig Pfaff
