I think you need to struggle with it a bit more :)
The problem here is that the encodings used by your external gear are
all .. well ... encodings.

none of these correspond to a simple stream of N different PCM
samples. if your starting point is, say, a 7 channel AIFF file, you
simply don't have the data in the format that these devices require.
it would not suprise me if there are plugins that can encode to one or
more of these formats.

that's a good question. but i suspect its simpler than that - i
suspect that the need is just not that great. the audio stream on a
DVD is already available in an encoded format and thus it just needs
to be delivered over a suitable link. the number of people who have
their own unencoded multichannel audio streams and want to play them
back via this kind of home theater equipment is relatively small.
