I have checked the 990 settings and they are correct , as listed by gonk.
There are some other settings on the 990 when setting up the DVD and Video 1, I am not sue if turning different options on or off make a difference. I have not noticed anything different either way. As for the cable box and the blue screen we have changed the box like 3 times since installing the 990 and I get the blue screen with the DVD player too. That might be a switching issue.
The audio issue I have no idea why I can not get the cable audio to run through the 990. I know you guys are the best at cracking these issues. I hope it is just a minor issue and not the 990.
Thank you very much for your input.
