I just plugged my iPod into my MacBook Pro and it deleted all of my videos off of it and said "some of the videos in you iTunes library, including the video 'video name', were not copied to the iPod 'name of iPod' because they cannot be played on this iPod. 101 total problems.". All of the videos are iPod formatted and have worked perfectly on my iPod up until today. I tried resyncing my iPod, restarting it, restoring it, all to no avail. Now only my music is on my iPod. Any ideas as to how to fix it?
