pete9321: no idea...why use optical?
just go HDMI...seems more sensible to me...and feed the audio out of Tv to stereo...simple
Because this is the only way to get dolby 5.1 output from the unit. I tried this last night and only the dig/coax out worked. The HDMI only connection to my amplifier did not light up with the dolby symbol.
Tried a reboot, as the channel banner was stuck on the screen, but can also add Onkyo 576 receiver to the list that experiences audio dropouts on coax/opt out.
