Please excuse my ignorance but I need some help. My buddy is having Comcast Hd installed this week. Here is the problem: 1. The box he will get only has digital coax out. 2. His Sony receiver has 1 digital coax in, which currently is connected to his dvd player which only has digital coax in. Does anyone know of any company that makes a splitter of some sort? Once again I apologize for my ignorance. Thanks for any help!.
