They seem to think client device operation of streaming is less than that of a dvd player, by about a factor of 2.
The study assumes a set top box of some sort being used for streaming. It's no surprise to me that the energy usage of that is about half that of a dvd player.
However, with the number of people streaming on PC, and the number playing DVD on PC, it is a nontrivial point that they have excluded - the cost of running those devices. I bet the power consumptions of those devices are dwarfed by desktop and laptop users.
And something doesn't look right...3MJ for a set top box? A 500W pc would run 1.8MJ, unless I screwed that up.
