I'm not sure if this is the best forum for this, but here goes. The digital out on my Directivo was working fine (connected to a Sony receiver). Then I moved, didn't use the digital out, and had it connected to a Denon receiver (RCA jacks only). Today, I plugged in an optical cable to get the digital out again, but it's not working. I don't think it's the receiver or the cable, because the receiver and cable work with the digital out on my DVD player. I can see the red light coming out the end of the cable when it's connected to the Directivo. I checked the setting on the directivo, and it's set to output digital. I checked the receiver's settings and for the TV/DBS input and it's set to use the optical input. And, no, it's not muted. So, it's not working and I can't figure out why. Have I left anything out? Any suggestions?
