Exactly the same as they do today. In TrueHD a 7.1 mix carries an embedded 5.1 mix and adds a 2-ch extension that is subtracted out. DD+ 7.1 (on Blu-ray only) starts with a standard 5.1 DD core, then...

Correct. This "compatibility core" process has no bearing on the number of objects. The number of objects in consumer media is limited only by bitrate.

Quite. I worked with Jim Fosgate on the program launch. ;)

The things you describe do indeed happen when PLIIx decodes 2-ch sources. But not 5.1 -- the fronts are never touched.

In a 5.1 system, PLIIx does nothing with 5.1, 7.1 or 9.1 sources. Result is same as Discrete. In a 7.1 system, PLIIx does nothing with 7.1 or 9.1 sources. (I am leaving 9.1 in my answer even though...

I agree that the limitations of which you speak may well be true for this first generation, but it will not always be the case.

I was thinking of just 2 height speakers in 3 places: front, middle, rear. Those would presumably all be different sets of signals. If they are not different, it makes no sense to ask which are being...
