I've searched for the last few months, and have not seen what I need. I have two componets that have dig. coax out (dig. cable box, and DVD) but only one dig. coax input on my reciever (sony db1070). I've been just moving the cable back and forth, but this is both tedious and difficult. What I need is an A/B selction box for the digital coax cables. Anyone seen or heard of such a thing?
