The problem is larger than that.  As the parent message indicated, if you
turn off denoise then the error is different but the nuvexport still
fails.  I ran "nuvexport --debug" and tried to export to VCD with all
optional processing disabled.  The result were:

forking:
/usr/bin/nice -n19 mythtranscode --showprogress -p autodetect -c 1039 -s
2005-08-18-01-15-00 -f "/tmp/fifodir_18246/" 2>&1

forking:
/usr/bin/nice -n19 ffmpeg -hq -y -f s16le -ar 48000 -ac 2 -i 
/tmp/fifodir_18246/audout -f rawvideo -s 720x480 -aspect

-acodec mp2 -f vcd "./Pulp Fiction.mpg" 2>&1

I cut-n-paste the latter command to the shell and got the following reply:

ffmpeg: unrecognized option '-hq'

If I strip the '-hq' option then I get a more reasonable error (because 
the fifo is empty) but at least it accepts all of the command line 
arguments.

It looks like the mjpegtools people are innocent this time?  In any 
case, it might not be a bad idea if mythtranscode checked the process 
exit status of ffmpeg and threw an error back to nuvexport so it could 
end noisily.
