I have a Panasonic TH-42PD50U plasma television wired to a Direct TV Samsung SIR_TS360 high definition reciever. Here's the problem, the tv has hdmi and the reciever has a dvi connection, I bought a cable with a appropriate ends, and I cannot get the cable to work. I have everything working with component cables, but I would like to use this cable. I believe I have changed the settings on both the receiver and tv, but maybe I'm missing something! Any help out there would be most appreciated.
