Since the flight to San Diego today is 4 hours, I thought I’d rent a couple of movies off iTunes to watch on the plane.  I read the support pages about renting, reviewed my options and selected The Transporter and Juno.  $2.99 and $3.99.  After downloading them, it was time to sync them to my 5th generation video iPod.  Oh wait.  You can’t do that.  Rented movies can only be viewed on newer iPods.  Surely Mr. Jobs would tell us that, right?  Nope.  Nowhere in iTunes or in the support information provided by Apple does the company provide this rather helpful information.  Only by searching the user forums did I find this information and then only in the complaints of others.  Thanks Steve!
