[mythtv-users] Nuvexport and yuvdenoise problems

I'm running my backend on gentoo, and I'm trying to set up a user job to 
encode my recordings to xvid using nuvexport. No matter what I do, 
yuvdenoise is called no matter if I'm using noise reduction or not.  The bad 
thing about yuvdenoise being called is that it just sits there and takes up 
about 5% of my cpu, but does nothing. I am using mjpegtools 1.6.2-r4 from 
portage. Also, how can I run nuvexport as a non-root user? Here is the 
command I'm using and the output I'm getting:

nuvexport --infile=%FILE% --cutlist --path=/recordings/ --nice=19 
--mode=xvid +--crop -F

Here is my command output from my mythbackend.log

You are running nuvexport as root -- this is not advised.
Press ENTER if you really want to do this.
