"Degrade" is a loaded word, but there are many reasons why 
film-originated images are different from video-originated (in 30i or 
60p).  Among them are the frame rate and its presentation on your screen 
("2-3 pulldown" in the case of film or 24p video), grey-scale transfer 
characteristic, appearance of grain and its random characteristics (as 
opposed to the fixed-pixel grid of digital video), etc.  And all of that 
aside, your original comments on NCIS ("dark and murky") could have 
reflected an intentional decision on the part of the director.  Simply 
based on what's in the scene, it would be unlikely for sports or Leno to 
be "dark and murky."

ABC, Fox, and ESPN are 720p HD.  Everything else -- at least in network 
delivery -- is 1080i.
