I just set my TiVo to record tomorrow's White House Correspondents Dinner. My understanding is that the pre-show (arrivals, interviews, etc.) starts at 8 PM and the dinner itself starts at 9:50 and runs (officially) until 11 PM but will probably run longer. Those are all East Coast times. I'm on the West Coast so I'm recording from 5 PM until 9PM. That oughta do it.
