Watched 300 on Blu ray last night.
In the sound settings for this it gave an option of:
Dolby
Dolby TrueHD
PCM

I went with PCM as that sounded clearer and louder to me. What is the difference between PCM and TrueHD sound?
Also are there any other settings on the AMP you may change to improve sound on this bluray (I had it on neural THX)?

Picture quality wasn't as grainy as I have read on some posts here (only at the start and then it improved to great quality)
 
PCM is lossless, Dolby TrueHD is lossless compression....figure it out ;)

As for grain, it's not a bad thing. You get grain from film.
 
Sounds like the PCM setting is for the player to mix in the sound from Picture-in-picture content or commentaries, with the TrueHD setting for if you're just watching the film and passing through the audio to be decoded by the receiver.

PS3 can't pass True HD to a receiver, it decodes it to PCM.

I think that the OP was right to select the PCM track on the disc. There's no point asking the PS3 to decode a TrueHD track to PCM if there is a PCM track already on the disc.

I know, I have one :p

Where do you see him saying it's a PS3?
 
I did actually watch it on PS3 using a sony STRDG820 amp. and yes selected PCM as that sounded the best to me.
I also have the PS3 set to PCM sound anyway
