Here's what I've used, which is an ugly hack, but works like a charm :).
Add the following to /etc/rc.d/rc.local:
/usr/bin/at "now + 5 minutes" <<EOF
It isn't real-time, but will ensure your mythbackend is absolutely the
last thing to get started. You may loose 5 minutes on your recording,
but my machine rarely restarts (power loss + kernel upgrades only),
maybe once a month, probably less.
