Hi I just upgraded my Pioneer DV525 to the DV575a as I've heard good things about this player. The problem I'm having is getting the audio on my movies to output in 5.1 or DTS. Neither is working and I'm stuck. Initially, I thought I'd sussed it as I had not set the audio to output in 5.1 under initial settings, speakers. Also, I have set it as follows: Digital Out is On DTS Out is DTS Linear PCM Out is Down Sample On MPEG Out is MPEG > PCM Audio Output Mode is 5.1 channel. My Amp is the Yamaha DSP-AX750se Can anyone help?
