Hello, we just bought a new home where owner had home theater installed nicely in the living room. Cables were all concealed behind the drywall. A/V Receiver, etc were at least 20 feet away from TV, Soundbar, etc. His cabling was all DVI + Component wiring. Now we have everything based on HDMI. How do I run my apple TV, A/V Receiver over this set of cables? Do I need to have all these cable replace or there are converter to do these? Pls advise!
