Does anyone else have issues with Directv PQ on a HDTV? For some reason my new Sanyo HDTV has a great looking pic on OTA hd - when I compare Directv - DTV looks horrible. I thought Directv was an all digital quality pic and sound. It looked fine on my old analog Tv. I know this is partially due to the resolution capability of my new set- However it really makes DTV look bad.
