    From where did this video come? There are a number of encoders that use the .m4v file extension but that are not standard MPEG-4 files, so if you got this video from someone or somewhere else, perhaps you have one of those incompatible formats.

    You'll need to convert it to format iTunes can handle, such as a true MPEG-4 file. Without knowing the exact codecs used I can't be sure, but MPEG Streamclip might be able to convert that file.

    VLC will most likely play it. If so, use the info thing to use VLC with all m4v files.

    Do you have Perian installed? Adds codecs to QT. It may allow you play that m4v.

    I encountered the same problem after trying to rename 2 of my m4v-films in iTunes. iTunes crashed on the attempt to renaming, the film can not be displayed anymore and the preview of the film disappeared. After export of damaged file to desktop and trying to open with Quick time player there is a error: film cannot be opened; contains a wrong public atom (or so …). Different videoconverters and perian : no solution !
    Somebody knows how to repair those files ?

    Quicktime / iTunes / Apple TV throw up a lot of errors with M4V / MP4 files that other media players do not.

    I recommend downloading VLC as it is a much better media player than quicktime. If your file plays in that it is more than likely something simple with the Meta Data or chapters that is causing the error.

    To fix the M4V file without having to transcode, I recommend downloading Metadata Hootenanny (FREE) from http://www.applesolutions.com/bantha/MH.html

    Using that, add a movie chapter (VIEW > CHAPTERS) and save the file. It should save the file within a .mov container fairly quickly with the same quality video. You only need to save one chapter (more if you want) as iTunes stalls if it cant find chapter references in the M4V files. That .MOV file can be imported into iTunes and played on an Apple TV.

    More errors with MP4 files that cannot be imported into iTunes can be fixed by simply remaning the file extension from .mp4 to .m4v

    MP4 file that give the error " invalid public atom " when opened with iTunes can be fixed using VLC. Open the video with VLC and FILE > STREAMING/EXPORT WIZZARD

    Select Transcode / Save to file, then select video from existing playlist item. Ensure the video / audio transcode options are UNTICKED as you only want to quickly change the container to .mov

    Save the file and iTunes will be able to play / import.

    Is Metadata Hootenanny Mac only? I posted this same problem on the windows side to no avail. I need this exact solution for PC. Can anyone help?

    I had the same problem with a MOV file from a digicam. It did not play neither in QuickTime nor in VLC or Mplayer.

    After a deep google search I found the VRT Tool (www.grauonline.de), which does a rather good job in video repair.

    It's worth a try with corrupted video files.

    The PC version of the tag editor is called MetaX.  It's $9.95 and well worth it.  Once you add the tags, it will play in iTunes.
