So I picked up the new ps3 3d display tv and I saw that you need a cable box from your cable provider to watch tv shows in it. The problem is our cable is just a direct connection from the cable plug (or whatever its called) to the tv. It does not have a cable box. How can I watch TV shows in the 3d display tv now? Can I buy a cable box somewhere and connect it to the cable and then connect it to the tv with an HDMI cable?
