OT: surround

[David Myers <dmgraph@earthlink.net>]

A composer friend of mine has created a very long piece of electronic 
music (4 hours) and I suggested that he might try to get it released as 
a DVD-audio only disc.  He asked me about surround sound in this 
regard, and I must admit I'm in the dark.

Does anyone know of a way to expand stereo tracks into surround without 
reworking them track by track (and I don't think his work really has 
multitrack to draw on), maybe something which could introduce varying 
ambiences, etc., without requiring months of work?  It would just be 
nice to give his stereo stuff some more dimension if in fact he looks 
to produce a DVD disc.  TIA...
