Agreed, about the other two variables.

The man page for start-stop-daemon doesn't say anything about environmental
variables. It wouldn't surprise me to learn that when using --chuid (some of)
the environment is reset for security reasons.

You could add a line like this to your startup script:

     export PYTHONPATH="/mythtv/local64/lib/python2.7/site-packages/"

Using Upstart here, so can't help much with init.d scripts. Consider
dropping the --chuid argument and replacing it with --user *after*
mythbackend. Like: mythbackend --user you <all the other args>. That's
what the Upstart .conf file does.
