I am having an issue with the DVI video switching on my 990.

I have my DVD player connected via DVI/HDMI cable for video and optical for audio. I have my HD Cable box connected the same way to the DVI 2 input.

When I switch between channels the DVD video/audio works perfectly. The cable box's audio works fine but I never get the video. When I pull out the HDMI side of the cable to the cable box and plug it back in I get both video and sound. This tells me I have all the right channels assigned. For some reason it doesn't recognize the signal comming from the cable box. I replaced the cable box with a second dvd player and had the same problem so I don't think it is an issue with the cable box.

Sorry for the long email. Has anyone experienced a similar problem or have any ideas for a solution.

Thanks
