Only a small fraction of console gamers use video playback
We know that many parents who may buy game systems for their children are largely uneducated to the video game industry and all the functions available not only to their kids, but to themselves as well. Thus why people still have parts of their homes dubbed "dens" or "game rooms". The PS3 deserves front-and-center attention to a family's media center and these results reflect that many are not even aware of the awesomeness of Blu-ray movies. Or nobody watches DVDs on the 360 or the Wii ... well, the 360. Wii owners don't exactly have a choice.
