Being a TV installer, I have seen all the variations in cable boxes, all the different hookup possibilities, and all the differences in picture quality between the SD and the HD cable channels. The few DirecTV receivers I have hooked up are all SD boxes using the video output to some 1080P and 720P LCDs and a 720P plasma or two. A question: Why does an SD signal from an SD receiver ALWAYS (in every installation with a standard receiver using video cables) look worse on the new HDTV than the old CRT that is being replaced? (with either an LCD or plasma) No amount of tweaking can bring the picture up to the quality of a CRT. Now, before you start with the BS about not knowing what I am doing, I have had both the boss and the head technician from the store go to several of the installs and try to improve the picture. There is no improvement when they have tried. I am looking for serious input. Thank you in advance.
