Query: Good concert, average video quality

Madonna is very well known for giving amazing shows with non stop fun, and this is not the exception. The only bad thing that I didn't like very much is the quality of the video of the concert, while the Bonus: Behind the Scenes, has a cristal-clear image, the concert doesn't have it, it looks a bit blurry in contrast to the bonus features. I need to try this in another TV set, but I doubt that that is the problem considering that the extra feature looks well.After some time, the video is not bad, the problem is that it has a blurred effect to make look better everything on the screen.
