hi everyone,i have an onkyo 787 it is about six months old. when i put on the phantom menice dvd it doesnt go into dolby digital sorround ex or or thx surround ex it just stays at dolby d or thx cinema. it will decode dts es (gladiator) fine and all the sub menu parameters are set to auto decode. i called onkyo service and they said some dvd are not flaged and if there was sound coming out of the back speakers not to worry about it. so far i have tried phantom menace,terminator 2 ultimate edition, toy story 2 and seven ultimate edition with no luck. if anyone has any input or advice because i am not happy with what onkyo had to say .
