For the other two, however, all of the preliminary stuff on the disc seems to be in 5.1, but when the movie starts, my receiver display shows "PCM 48", and it is strictly 2.1.
The box for Gran Torino seems to say it has both Dolby True HD and Dolby Digital audio; the others are less clear. I assume this means the other two ONLY have the True HD or DTS HD soundtracks but lack encoding for the 5.1 sound, and as a result, neither the TV nor my receiver know how to decode it other than the smaller sound track.
Does this make sense?
And for my replacement receiver, to get around this, do I need a 7.1 receiver? If I have a choice, do I want HDMI from Samsung to receiver, then HDMI out from receiver to TV? Or do I want to just let the Samsung decode the audio and use the 7.1 analog outputs?
Does the receiver you are using now have internal decoders for TrueHD and DTS Master audio as well as an HDMI input with v1.3 repeater? Either way you need to change your wiring scheme around just a bit and I highly doubt you will need a new receiver even if it can decode the high resolution audio codecs and doesn't have an HDMI 1.3 (that's the beauty of the 3600!).
So here's what you should try. Regardless of what your receiver can do you need to run the hdmi out from the 3600 to your receiver and then another hdmi from the receiver out to your tv. And depending on your receiver capabilities you will need to set things up one of the following 2 ways:1
Receiver can decode high res audio and has v1.3 hdmi. Set your 3600 to "bitstream audiophile). With this setting the 3600 will not touch the audio signal and send it completely undecoded to your much more capable receiver to do the job. With this setting you will see displayed on your receiver whatever the audio info on the back of the disk you are watching displayed (i.e. dts master, truehd, dolby digital, it just depends on the source). This is the optimum way to set it up as you also get to enjoy all the added bonuses having a receiver offers like prologic, speaker calibration, individual level controls, etc.2
Your receiver cannot decode high res audio. Set your 3600 to "pcm." All that means is that your 3600 will do the decoding and send the info to the receiver which is now just a workhorse (slave) to the instructions it gets from the 3600. This setup is the exact same as if you were using the 7.1 analog outs on the back of the 3600, but instead it just passes it to the receiver thru the hdmi cable instead of having to use a handful of rca cables. You will also need to setup the "speakers" in the 3600 menu according to what you have (set everything to "small" that does not have a powered subwoofer in it regardless of the actual size of the speaker). All receiver settings and calibrations will be ignored with this setup and the display will not show trueHd or master audio but you will be getting identical quality audio anyway because your 3600 is doing the decoding.
Hope this helps. I know audio has gotten to be very confusing in recent years and that is in large part to keep the consumer thinking he needs to buy newer and better equipment when in fact a little time spent researching can be far more valuable and much less expensive. I personally hate getting "tricked" into spending more money with my own apathy. But if you actually do need/want to get a new receiver, God bless ya
