Info Wanted: Phantom Edit m4v to mp4?

I don’t have Apple TV or iTunes. Can I just rename the m4v extension to mp4 to play in Quicktime or Real Player?

Was Attack Of The Phantom ever put out in m4v or other non-burn file format?

Isn't an m4v just an mp4 file with a different extension?  You can't play it in QuickTime?

I don't see the harm in trying to change the extension to mp4 - if it doesn't work you can always change it back, no harm done.

Thanks for replying. When I selected File|Open File menu option, Quicktime didn't include m4v files as Movies in the file dialog, so I thought that it didn't play m4v files. I went back to Quicktime and changed the file dialog to All File Types, and then it does see m4v files as Quicktime Movies. I haven't tried yet to play the file.

Re: Attack of the Phantom, does anyone know where to get the m4v version? The one torrent I found isn't seeded anymore.
