I don't think that mytharchive ever attempts to perform such a command.
 If I enter the above command on my system it fails as well, which is

When mytharchive (mythburn.py) runs jpeg2yuv, it uses JPEG images that
were created earlier in the script.  There are a number of instances
where the JPEG files are created, but for example:
bgimage.save(os.path.join(getTempPath(),"background-%s-f%06d.jpg" %
(page, framenum)),"JPEG",quality=99)

You may wish to post your entire mythburn.log file or a link to it.  I'd
also say to make sure you have the latest mythburn.py, but I can't say
that I've had your problem even when I was running 0.21 or earlier versions.
