Newbie here...got the 622 installed on Friday and played with it this weekend. So far I like it a lot, but I have one question. On Sunday I recorded the NASCAR race on TNT HD. When I watched it later, I didn't have any sound using the optical out from the 622 to my receiver. I had sound via RCA cables from the 622 to the TV and I had sound from the TV to my receiver, but nothing with the direct optical connect from the 622 to the receiver. I pulled the connector out of the back of the receiver and it was glowing red, so I had signal but apparently it had nothing in it. I have DD/PCM enable in RF mode on the 622. Is there something I have to change to get this to work right? I have not tried any other channels or done anything other than enabling DD or PCM on the 622 and I tried every combination of those settings with no success.
