dvd sound with mmcs
 

Is there any service menu adjustement i can do to have a louder sound while playing dvd in the mmcs? the sound is not loud even at high volume.
i try putting on and off the drc ( idon't know the exact term in the menu) but i don't see any change or not much of a change. i notice if i listen to a dvd with 5.1 and 2.0 audio track, the 2.0 with sound a little bit louder.
Yesterday, i was listening to a dvd concert and i had to put the soud at max and it was roughly less louad than the fm at half...
So is there a service menu i can adjust the db or somekind of other adjustement for teh dvd playback? i search with the service menu (set+menu) and foud nothing related to svs playback sound.

i just checked and by drc i mean dynamic compression range
