Apple TV and 970 DVI input/output

I got an Apple TV and have connected the HDMI out from the AppleTV to the DVI input on the back of the 970.

Then connected the DVI out to an HDMI input on my TV.

I cannot seem to get the video from the HDMI/DVI to show up on the TV. Also, where do I configure that in the 970 to assign an audio out?

Thanks in advance.

Run an S-video cable to the TV from the 970. That should allow you to see the menu and the configuration screens. Follow the guidance in the manual. If you don't have a manual you should be able to download one from Outlaw in the archives.
