Watching video in the iPod app offers some great features, some which appeared with OS 3.0, but only if you’re watching in the vertical orientation. You can use the new 30-second skip-back button, and sicne this is a podcast from iTunes Store, the email button appears to easily share a link for the show with someone.
But if you rotate your device to the horizontal format, which most users probably do for watching videos, most of these features disappear.
