TBS HD on both 95 and 200's confirmed how much better mpeg4 is over mpeg2. It was obvious watching channel 95 (mpeg2) how terrible it was in dealing with fast moving scenes - the pixelation was TERRIBLE. I cannot stand to watch basketball on TNT HD (in the 70's) or for that matter the concerts they show in the low 100's. Have you seen the what the flash of lights look like during a concert - a bunch of huge pixel blocks. Or when the Bulls are in a fast break and the camera is panning quickly to cover the action - you can't even see the players clearly until the camera stops moving. Watching MLB on TBS HD in mpeg4 (in the 200's) restored my faith in compressed HD over satellite. During the same fast moving scenes, mpeg4 didn't pixelate the scenes. Instead, it may get a little grainy or soft, but overall, it still looked spectacular. I am not saying mpeg4 is better than mpeg2 on stationary scenes or slow moving scenes, just the fast scenes, which is basically the foundation for any sporting event or action flick, so unless you only are interested in watching Sunrise Earth, mpeg4 is a blessing.
