Would anyone know if you can use the MCD183 as a normal DVD player,my standalone player as just packed up and my partner has this MCD183 system.

Have tried to connect the audio output from the unit to the input on my Sony 5.1 AV receiver but there is no Audio output from the Sony amp speakers, everything is set up correctly but am just wondering if it is not compatible with the amplifier within the unit

Any assistance gratefully appreciated
