Using the Windows Phone 7 Connector for OS X can prove to be a drag when attempting to transfer a movie from iTunes to your handset. The progress bar gives the false impression that it's stuck and one tends to get frustrated, especially if you're like me and only synchronise your device just before you leave the house.
OS X user Marin got in touch with us to let everyone in on a more efficient way to transfer movies to your WP7 handset and not having to wait 20 or so minutes. Should you have an avi copy of the movie at hand with an mp3 soundtrack, you can use software such as MP4Tools to convert and then import into iTunes. Windows Phone Connect should then pick up the movie and be able to transfer it to your device with much more efficiency.
Unfortunately, Marin noticed a drawback to this method (which I can confirm). The movie wont be playable in iTunes (as well as Xbox 360 consoles) and a stand-alone media player (such as VLC) will have to be used. But this should be no problem if you have a separate m4v copy. Let us know if this guide works for you and how it compares to transferring m4v movies to your device.
Thanks Marin for the tip and guide!
