I have recently done some ripping and converting of TV show DVDs via MacTheRipper/Handbrake. For whatever reason, some of the shows are not compatible with my iPod. What is weird is that it is somewhat random and while some in the batch I encoded work perfectly well, some don't work at all. And since iTunes doesn't give you the specific reason why they aren't compatible, I have no idea why it is the case. Is there any reason why some would work and some wouldn't when they are all encoded with the same settings (and most of them at the same time)?
