Has anybody ever had an issue where iTunes somehow "forgets" it's already synced a video to an iOS device, and re-syncs it every time? I'm having this issue with both my iPhone and iPad (both running the latest release of iOS 6) and iTunes 11.0.5 (it happened with 11.0.4 too - it's been going on for months). It only happens with some videos and not others, and I haven't been able to find any real distinction between the ones that get constantly re-synced and the ones iTunes only syncs the first time.
