If you're looking for a DVD player that visually delivers... the Sony 550D should be at the top of your list!  In a single word... WOW!  Vivid colors leap off the screen, shadows appeared as shadows and not dancing black  pools of fast moving artifacts.  Lip Sync problems... not with this  particular machine!  All the lip sync problems must have been ironed out  with earlier versions of the player, as this one hasn't had a problem yet!  The only area that the 550D doesn't do so well in is in CD play back.  The  Toshiba 3109 with HDCD capabilities outshines the Sony, but if you're  looking for outstanding CD playback, why look at these DVD players?  Get a  dedicated CD player from manufactures such as Meridian, Wadia or Cary?  If  you want the best in VIDEO, then look no further and pick up the Sony 550D.
