How about taking the repetition out of these shows?
Five minutes into the show there's a break. After the break is 90 seconds of repeat of what was said before. These shows that last an hour have about a half an hour of show, sometimes less. Sometimes a really interesting topic is killed by having to sit through the program twice all at the same time!
