watched film on satellite ,film was dolby surround, sat reciever is not linked to 3802 by phono (sat reciever is conected to nicam s-vcr, vcr to 3802 via phono lead to 3802 vcr input) set vidio to sat channel, engaged pl2 c on 3802 ,no sound from surrounds in pl2 at all, set amp to 5 channel sterio ,there was sound from surrounds, any ideas why not in pl2 in this case, if using vcr ,digibox, tv pl2 is ok ,bit baffled ,something to do with dolby surround thank you
