I had a similar problem and invented a similar solution.
The only difference is I put the wait_for_hdhomerun and the
rest of the script (starting mythbackend etc) in a subshell so
the rest of the boot doesnt wait for it

This is Fedora not Ubuntu so YMMV

e.g.

wait_for_hdhomerun
/usr/bin/mythbackend
more stuff

changed to:

( wait_for_hdhomerun
  /usr/bin/mythbackend
  more stuff
) &

HTH
