I did 3 hours once with Coach Troy's Tough Love video. I'm going to have to do it again this winter. I like the DVDs where I can turn off the music and listen to my own stuff.

I did 2.5 hours once using two different videos - Mental Toughness and Hillacious. That worked well because I used the change of video break for the bathroom and to refill my water bottle.
