Two new releases make it to the top of this week's Nielsen VideoScan chart courtesy of Home Media Magazine. But even though Blu-ray sales were up 21.71% this week over last, it wasn't enough to help Blu-ray obtain more than 5 percent of the top 20 sales. This, like the past few weeks, has mostly been because half of the DVD top 20, still aren't available on Blu-ray. The big titles on DVD that are missing this week, are the first three Indiana Jones movies, which are evidently very popular thanks to the fourth movie hitting theaters. We can't wait to see how -- or if -- the market share changes with Paramount Blu-ray titles coming out in the coming weeks, and finally Universal in July. Of course that still leaves Weinstein exclusively releasing on DVD, but this only accounts for one of the top 20 DVDs this week. For whatever reason HMM didn't have its new market share per title chart in this week's edition, but we sure to hope it's there next week when the biggest day and date title for Blu-ray in some time hits the streets in the way of National Treasure: Book of Secrets.
