I didn´t have sound in Channels 1 and 2 with Pan Type set to “Constant Power”. I mean, there was no audo sounding while the peaks were there, and that channels were empty in the rendered wav. When i changed the Pan Type to “Film” or to "Add Channels (0db Center), that FR and FL channels have sound. My question is, if i want to keep the pan intact as it is on the Blu Ray, which pan mode is the correct? I just want to keep the 5.1 Ac3 Dolby Digital True HD exactly as it came on the BR. I see that “Pan Type Film” moves the speaker symbol to a middle point between the center and FR speakers in the FR channel panning, between the center and FL speakers in the FL channel, and so it goes…, while the "Add Channels (0db Center) " is just putting the marked rhomboid symbol in each speaker. Do you know which way is the correct to keep the channels intact?
