The Ceton InfiniTV 4 USB is one of the cooler items we're featuing in our 2011 Holiday Gift Guide. It basically turns your computer into a fully-functional live TV DVR. We know that features like Media Center exist on PCs, but the problem is that, until now, it's been hard to get a good signal into your computer. The InfiniTV 4 USB fixes that. It's a CableCARD adapter that plugs into your machine using USB. So all you need to do is insert a CableCARD from your cable provider, plug in your cable cord, and plug in to your computer. From there, you'll have access to all of the cable channels that you subscribe to, and you can record up to four different channels at once. See? We told you this was cool. Great for rooms where you only have a computer and no television, but also great if you want to incorporate a Mac or PC into your home theater setup, as it eliminates the need for a cable box, meaning you save on that montly rental fee. The Ceton InfiniTV 4 USB sells for $299, but you can get one on Amazon for $269, saving yourself 10%.
