I just bought a Sony 1252Q on Ebay, along with an IFB-11 input board. $240 US with only 629 hours. My question is, to convert a signal from my progressive scan DVD player and my HDTV cable box, both which output 3 component(YPbPr), to my RGBHV 5 BNC inputs, what will I need? I have heard ATI makes a converter from DVI -> RGB, but I'm not sure it will go both directions. Any suggestions would be appreciated.
