    I'm trying to understand the difference between M4V and MP4.

    I have an MPG which I can convert to MP4, but then iTunes will only store this under the Video section, it wont let me store it under the Music Video section.

    I even converted it to a M4V, but it would still only let me store it under the Video section.

    Any idea why?

    Did you try command + I > options > media kind > music video?

    You can't reclassify it as TV or Music Video? I don't believe I've had these issues with mp4 files.

    I have a PC, but yes that worked!

    Thanks a lot. It seems the mp4/m4v doesnt really matter.

    Still not sure what the difference between the filetypes is though :)

    Not much. 'M4V' is basically an 'MP4' that is labeled in a way to make iTunes think it owns it.

    Of course, iTunes can play MP4s as well.

    I'm pretty sure you can just manually change the file types back and forth yourself and it won't have any effect.

    They are almost the same files apart from another difference.

    If you use Handbrake on a Mac to rip a DVD then the M4V file can contain Chapter Support.

    If you choose not to have Chapter Support in your movie then Handbrake changes the file to MP4.

    iPhone's support Chapters in movies.
