Is anyone else having problems with this? I have a very basic set-up, and have taken my old Kenwood receiver completely out of the loop. I just have Coax into the HD-STB, HDMI from STB to the Sony BlueRay/GTV device, and HDMI from that device to a HD TV. I've got a picture, but no sound. I found one reference to this problem that said it was a compatibility issue, but I have a hard time believing there would be this big of issue with a major cable providers STB. I'm taking the Sony device back tomorrow if I can't find a resolution.
