I’ve hunted in vain for command line pograms that will create them, automator actions and the file structure so I might be able to build them myself.
I’m currently doing this (even though I think it’s a lousy idea) on my Linux server. The command line I’m using is:
.avi .mov && mv .mov .m4v
I would really like to have this built in! I do not want to convert all my files (1.3Tb) and risk loosing information or compability with my other players (XBMC do read QuickTime movies, but…)
