Thanks Nora. As you can probably tell (between this and my "lock fullscreen" suggestions) I'm having a bit of an problem keeping DVDpedia in fullscreen mode. I use it to serve up my film library on my home theatre and sometimes there are issuses that pop up and knock DVDpedia back to list view. If this happens in conjunction with a crash or a system shutdown/restart then the app doesn't restart in fullscreen view. Thus, a simple AppleScript to check if fullscreen is active and, if not, activate it would be quite useful.
I'll hold out hope, but I won't hold my breath
