Ubuntu 12.04 using Mediatomb with WDTV media player.

When I restart the computer mediatomb still shows the music folder I scanned. This is in the HOME folder. But it never remembers the movie folder I set it to autoscan - this folder is on a separate hard-drive in the same computer.

I'm guessing that it's because the other drive doesn't mount at startup, so I used system>admin>automount to set it to mount at startup, but mediatomb still forgets it each time.

Is there a way I can encourage mediatomb to remember which folders to scan when I reboot?
