I don't know if this was because of settings on the PS3 side or the way the 01 handles PCM. I'll have to experiment.
From what I have read, this is a glitch with the PS3 not the AVR.
PS3 sends out max channels selected, so,
If PS3 has a 7.1 selected and the source is 5.1 = The PS3 will send 7 channels PCM = 5 channels with sound, 2 channels no sound. The AVR sees 7 channels and therefore will not apply any matrix processes.
Should be the same for 2 channel sources.
So now, you need to look at every movie (cd) to see if it is 2 channel, 5.1, or 7.1, and go into the PS3 and uncheck any settings higher than source material.
