     A decorder is either a special plugin/codex that gets  installed 
into the OS ( codex called a52dec)  and decoding happens internally.
     or a  hardware device like a stereo receiver that is able to 
understand  Dolby Digital signals from the DVD through S/PDIF connector 
from  the sound card to decorder.
     however, it only appears you are only missing a52dec?  Have you 
installed a52dec from ports/audio/gstreamer-plugins-a52dec/ ?
