Movies may well, of course, have been encoded with multiple passes  
using the best gear available. Live events, must be encoded in real- 
time, and even with the best gear that limits what you can do.

Add to that the MPEG transport used by the networks and you have MPEG  
artifacts that any discriminating viewer will see, most often in  
unpredictable motion like sports. Even the SuperBowl was full of such  

Get used to it. Our parents lived with "snow" and we will learn to  
live with "artifacts".
