First, correct and standards tags exists for 3gp, so itunes tags should
not be written for 3gp, nor for mov since equivalent exist.

Then, as a general attitude, Im against writing non standard features in
perfectly defined standards.

If the user wants them he can use -f ipod format, we are not removing
support for metadata. We created a specific format for this, please
let's use it and stop spreading that mp4 is ipod/itunes format.
