my rdr-at107 dvd recorder does not eject unless they tray has a disc in it. the player simply will not eject if the tary is empty. any suggestions other than always keeping a cd/dvd in the ttray? also, is the coax-digital audio output disabled when i connect the recorder to my tv using the hdmi output? (i like to get surround sound from my receiver,whech does not have hdmi inputs.)
