Fans of high definition video may be swayed to the service, but there are some strict limits on who gets to use it.
The good news first. The folks at CinemaNow are providing 1080p video rentals to your PC. Pretty slick, especially since most rental services either limit to 720p or just plain don't support HD video on the PC - we're looking at you Vudu!
The bad news is that, inexplicably, you'll need to have a second-generation Intel Core processor in order to use it. That means anyone using Intel's 2011 Core i3, i5 or i7 processors will be able to watch the videos and everyone else is out of luck.
It's a deal made between the companies clearly, since it's difficult to think of a technical limitation that would disqualify an AMD or older Intel Core processor.
