We've had our Bravia for just over 3 1/2 years. Yesterday we put on a brand new DVD from a boxed set, and the picture and sound started jumping around. We tried out the DVD on our other telly (Toshiba) and it worked fine. We retried the DVD again on the Bravia a few hours later and it worked fine, as did another DVD from the set. Today we inserted another DVD from the same boxed set and ir refused to play and the DVD player doesn't respond to commands to eject, either via remote or manually on set. Is the Bravia player gone or is there something amiss with the DVDs? Can it be fixed?
