Re: But how lossy? I wasn't talking about DISH and/or Directv -- who use MPEG-4 and various patented variable field compression Magic(tm) to reduce the bit rate even more. Or Uverse who use low bitrates and smoothing (aka "blurring") to reduce their bandwidth. (if all you watch is Uverse, you won't notice it.)
I was talking about ATSC (over-the-air) and CABLE broadcasts -- which are MPEG-2, still.
