I think I understand what Tom said, just want to double-check. The 
technique you describe is for encoding in dolby prologic, yes? If so, 
would you do anything differently for a discrete multichannel release?

Re-reading your description again, not I'm not sure I follow. Let me 
re-state it and Tom, please tell me if I'm wrong:

Start with an un-decoded M/S signal.

Decode the signal to stereo, route this to the rear channel.

Decode the signal to stereo again, but with more center mic, route 
this to the front stereo channels.

Drop the level of the rear by 3 dB and run through a Dolby Pro Logic Encoder.

Have I got this right?

Just as an aside, I've been having a great time composing 
multichannel mixes by taking a number of stereo recordings from a 
site and re-building the environment from its components. To do this, 
I try and gather a number of different mic perspectives to highlight 
various soundscape elements, then assemble a piece from that. Not a 
snapshot of an instant in time, more of a collage, but I'm happy with 
the results.
