Hi there...

Sorry not to contribute to this thread earlier, I've been busy.

If you are wanting to distribute a "quad" G-Format (ie decoded from B Format to speaker feeds) recording, I'd recommend DTS-CD format. The encode software is inexpensive; it appears to have some advantages over AC-3 for Ambisonic-derived work; you can distribute files or CDs; the free player would be VLC (http://www.videolan.org/vlc/) - and of course virtually any modern home theatre system will also work; and here's a paper on how to do it (and the pros and cons):

You can ignore most of the stuff prior to Page 5 as you already have the quad decode.

I hope this is helpful.

Best,
