Q: Unable to sync Videos to iPod Touch 1st Gen

Hello, it happened to me before - except its my iPod 4th Generation. Most of my videos or movies can be synced though, there are only a few that doesn't work. I'm not sure about the cause of the problem, maybe something like the iPod and the movie format is not compatible or something.. If you tried almost everything and it still doesn't work, maybe try creating an iMovie project and import your movie into it, then just export the iMovie so it puts the video in another video.. Not sure if it'll work, but worth a try

Hope this helped!
