I've been reading posts here and it seems that the signal coming in through direcTV has been dissappointing to most. I'm in the market to buy a sony home theater system including the xbr40 inch HDTV. I was under the assumption that i would have a great picture if i hooked it up with the sony HDTV direcTV receiver. I understand that there are only a few channels that offer the HDTV singal but if there is anyone out there has this sony setup can you offer an opinion/s on your experience. Right now i have a 40 inch direct view mitsubishi with a generation 3 direct tv receiver. Will my picture improve at all going with the sony HDTV setup? thanks for any help. I'm new to the HDTV world so i will continue to read.
