Watch out, Netflix and pay-per-view: You have some serious competition from the Xbox 360. Microsoft is reporting that video-on-demand monthly sales have been doubling month over month and are up more than 70 percent since last September. More important for videophiles is that much of the content available is high-definition, and the Xbox Live Marketplace Video Store now has a larger library of HD content than any other service.

New content is being added all the time, too. And while some of it is impressive, a lot isn't all that new or exclusive. Movies such as Unforgiven, Training Day, and March of the Penguins, along with seasons one and two of Grey's Anatomy and Desperate Housewives, aren't exactly what I'd consider "must see" at this point (especially because I've seen it all before). But it's still nice to see the library beefing up its older content. Even more impressive is that series such as Robot Chicken: Star Wars will be an Xbox Live exclusive before it heads to DVD (not that you can't find it on... oh, say, YouTube). And new episodes of South Park will arrive on-demand on Xbox Live in March.
