In looking at Comcast Cable (Delaware) on my new Panasonic 47 in. I am amazed at the difference in certain channels. I only have basic cable (Not Digital or HDTV). Last night I was watching The Guardian and the picture , though not great was quite good. Fleshtones looke smooth with very little graineness. I am just amazed at how much it varies from station to station and sometimes show to show. Now here comes my dumb question. Is the fact that The Guardian is an HDTV program make it a better quality broadcast even on basic cable? I anm just curious as to what is the explanation as to these differences I'm seeing. Thanks.
