Hey, I recently bought a Samsung LCD HDTV and got a HD DVR Box from Comcast. The tv actually came with a home theater system and I wanted to setup TV audio by using a digital coax cable from the Cable DVR Box to the DVD player (which basically manages all the audio through the speakers). The problem is, I can't get it to work. Is there some setting from comcast that I might be missing? Interestingly enough, when I try running regular red and white audio cables from the box to the DVD player it works.
I'm using a Phillips Home theater system and it works with the red and whites on its "TV" audio setting. I've messed around with other settings with the coax but no luck.
