I have this same exact problem. Ever since they updated their software my optical audio connection does not work to produce dolby digital sound. If I unplug my hdmi cable dolby digital sound comes through, however I have no picture Go figure. I have no idea what they did within their software to warrant this type of error, but its annoying as I cannot enjoy true dolby digital through my current set up and IM NOT going out and buying a new receiver!
