I searched the forums but couldn't find my answer, so maybe somebody here can help me out. I have two HD sets in the house, and my Comcast Digital Cable HD channels I think look pretty good. However, when a solicitor called from Dish Network yesterday, he said that Digital Cable HDTV was not "true HDTV" and that satellite has the best quality while providing "true HDTV". He said that with cable, by the time the end user gets the product after miles and miles of cable, the signal quality is much reduced. Was this a salesman just trying to get me to try Dish Network or does he have a point? Also, does cable compress the signals more than satellite? I'm just trying to get the best quality out my new Samsung plasma I purchased. I like my cable, because for no more money up front, I get an HD box that also has a DVR that records HI Def programming. To get that equivalent from DTV or Dish Network, you need to put up $$$. Thanks for any and all help. Mike S.
