I'd love to see "I, Claudius" re-broadcast -- or better yet, be available on demand. When I was watching John Adams on HBO I thought, "this is the kind of thing that should be on PBS." I wish I could go to a PBS area of my cable on demand service and just pull up a cornucopia of stuff, from dramas to quirky arts and culture shows....and shorter-stuff, too...I don't always have an hour.
