Sony was supposed to offer full-resolution downloadable movies for the PSP, but the service has never come to fruition, citing "DRM problems." On the GDC showfloor, I overheard one Sony employee talking about how there's one giant stumbling block for Sony's potential movie download service: Disney. The giant media corporation doesn't want to make its catalog of movies available to Sony, most likely due to restrictions caused by their deal with Apple's iTunes Store.
But, why not go forth even without Disney's backing? Surely, Sony Pictures' vast library of movies would be more than enough to satiate a PSP-owning movie lover's tastes. However, as Connect proved, a half-assed attempt at digital distribution usually ends up quite fruitless.
