What i want (and i belive users as well) is a "universal" format which
can be used everywhere. That doesnt mean ipod tags should be in -f mp4 or
-f mov but that there is a -f foobar that contains all tags of all variants.
I prefer if i dont need to have each video 3 times so it can be played on
3 different players.
