Kinda offtopic I'm afraid, and it doesn't really help you, but I decided 
nuvexport wasn't flexible enough for my needs (although I haven't 
experimented with it enough to give a qualified opinion) and decided to use 
trusty old mencoder instead (although, again, never tried to do mono with 
it, but I imagine downsampling stereo to mono is well within it's grasp)

As another aside, I'm busy learning PHP at the moment (two days into it and 
it's wicked fun) and am considering writing an add-on for MythWeb that'll 
allow you to call and configure mencoder to do transcodes once I'm good 
enough; the companies workflow management system has gotta come first though.

(P.S. if anyone thinks this is a good/stupid idea, say so!)
