Serious suggestion: stand while you watch the video (Youtube on a TV helps here), use a pomodoro timer to do it in bits.

I also find I can watch a good bit of a complicated/technical video while walking on a treadmill/stairmaster at the gym. Just enough noise of other people, and the determination to do 45-60 minutes on a fitness machine replaces the determination required to get through a video. Doing it 3 days in a row feeds the motivation cycle in me. After day 1 I'm itching to get back to the gym and get back to the video to do another "episode".
