For #1, you could add a "sleep 5" into /usr/bin/mythfrontend (probably
around line 17). That will cause it to wait an additional 5 seconds
before starting the frontend. There are more elegant solutions you
could do, but that would be the easiest.

For #2, is the backend and frontend on the same machine? Because
mythmusic doesn't use storage groups, so the files would have to be on
the frontend to be played back.
