Sony DVP-S330 DVD Player
330 Has Lip Sync Problem
I just contacted Sony's customer service line and found out that all DVP-S330s manufactured before 8/99 have lip sync problems in random players, so make sure your 330 was manufactured after 8/99 otherwise it's a crapshoot.  I'm returning mine now.  Strangely, Sony has no recall  procedure in place because they claim that not every 330 in the batch  manufactured before 8/99 has had a problem.  I think they should inform the  retailers anyway!  Well, at least you know now.
