Sony DVP-S550D DVD Player
Another Recipient of the C-13 and No Disc error
I could not be more dissatisfied with this DVD player.  I deliberately bought this higher-end (at the time) player to avoid problems like these.  Thank goodness I bought a 5-year warranty on it.  So far I have taken the player in 4 times, two times ago, they replaced the entire optical laser unit and it still resulted in the same problems.  It skips and freezes during every movie now.  I have friends who have also had problems with Sony DVD Players.  Buyer beware!!!
