That Pineapple Express is obviously pretty good stuff as it not only moved enough discs to take the number one spot, on the Nielsen VideoScan charts courtesy of Home Media Magazine, but it also outsold the mighty Dark Knight by almost three to one in its third week. Seth Rogen's latest comedy also topped the new Blu-ray rental chart -- which is new this week and posted after the break. For now we're going to skip posting the top 20 market share chart because it's useless until Nielsen will provide HMM a version without all the catalog titles. Blu-ray's top 20 market share was down this week to 13 percent, which would normally be a good week if we weren't comparing it to last week's record breaking 16 percent. At this point we're tempted to predict both formats being down next week, but after Pineapple Express surprised us this week, we'll wait and see how Appaloosa does rather than risk looking stupid again.
