I have run across a first generation Mitsubishi HDTV that requires an RGBHV signal, but the new Scientific Atlanta DVR that Warner Cable is offering us here in Houston only has DVI and Y-Pr-Pb outputs...

Mitsubishi makes a box that strips the HV signal from the Y line and splits it into the H and V lines... It's $300, and there isn't anyone around who can wholesale it...

Does anyone know of another manufacturer that makes such a beast, and where it can be easily found?
