If a Blu-Ray disc does not have 2-ch PCM output, now what?

My present setup is simple 2-channel audio and I'm using the Sony PS3 game console for Blu-Ray movies. I use the digital optical output from the PS3 into the DAC section of my Accuphase CD player.

I sometimes use this feature for other digital source components like low-end CD changers as I can get higher quality audio output from the Accuphase.

I was watching a Blu-Ray disc last night (Gone Baby Gone) but the only selections in the disc's Audio Setup menu were Dolby Digital 5.1 and Dolby 5.1 uncompressed. The Accuphase DAC locked onto the signal but I'm not sure what I was listening to.

Was I missing some audio information in the movie? I know the Accuphase can't put out 5.1. It's simply 2-channel. Many other DVD's and Blu-Ray discs offer a 2-channel PCM setting but not this particular disc. We still enjoyed the movie but it's nagging at me that we may have been missing some audio. Did everything get mixed down to 2-channel somehow?
