We're having trouble opening m4v files which have been exported from within imovie using
mobile device paramters, when accessing those exported files on the documents pro device in the safari browser on the ipad. The movies try to play in safari but we just get a no entry symbol over the play button.
does this indicate a problem more specifically with safari's ability to play m4v media ? We've
tried changing the extension of the file to mov and mp4 still no joy.
