Tip: load iTunes U videos as 'Photos'

On the iPhone and iPod Touch, videos captured with the camera go in the 'Photos' app. When viewed, you can get a timeline of thumbnails, helping to navigate in the clip.

You can load other videos this way as well, including iTunes U videos or WWDC videos. The thumbnails may be useful in finding the right point in a class or series of slides.

Just import them into your device using the Photos tab in iTunes.
