Typically the 5.1 direct inputs are used for a DVD-audio or SACD player. Current copyright laws do not allow those players to output their high resolution tracks via digital outputs. You can also use the inputs for regular DVD if your player has the output. Most people use a digital (ie

ptical or coax) for DVD playback.
