Composite and s-video is not good enough for HDTV. Why not ask direcTv what is require or you maybe paying for something you can't use.
Just bought my new TH-50PHD7UY and should be here any day. I'm also waiting for my new Directv HD to be installed. Considering this TV only comes with composite video and S-Video ports only, what's my best option to maximize my video and audio quality? Should I add the DVI or the HDMI modules?
