Title says it all. I need to run a 50ft high speed cord from my media closet PS3 to my Samsung 3dTV as my receiver is only 1.3 passthrough, and then an optical cord to my ps3 for sound. Monoprice deosnt make such a cable so can I buy 2 of these http://www.monoprice.com/products/pr...seq=1&format=2 and then use a coupler or a repeater? If I understand right a 1.3 cord will not pass HD and 3D. Would like to order something ASAP. Anyone know what should work?
