Not exactly the same, but I often watch TiVo'd or otherwise-DVR'd content; I might start 30 minutes 'behind' on a 3 hour event and have a very, very hard time 'catching up' to live -- I pause for my bathroom breaks and grabbing food or drink, and find that I need almost as much time away from the content as the commercial breaks (which I'm skipping) would have offered. It's still nice being able to choose when to take those breaks, however.
