I am finally getting a 3D. (thinking about going with an LG passive system) my question is this. I use a Sony home theater in a box system and I routs my PS3,Xbox and Direct TV system into that and then one HDMI from there in to my current TV. When I switch to 3D TV will I still be able to do that?? I know I will prob have to get new HDMI cables. But can I still run in through my surrond sound system?
