adaptors for BNC termination to RCA
I have Wireworld video component wire with BNC at the DVD end. THis worked fine for my Theta but now I have an Esoteric DV 60. Does anybody know where I can find adaptors to make the connection. I also tried HDMI and so far can't get the communication with my HDTV to work. Any help out there??? thanks
