Samsung DVD511 DVD Player
2 Samsungs 511 with the same issue
We received the Samsung 511 DVD player as a gift. We also received a new Un-opened DVD with it. No scratches, or damage on that DVD. That very first movie presented the skipping problem. It was so bad, we had to take it back to the local dealer for an exchange.     The new one we received was great for the first movie. Then a rented one presented the same problem as the other unit. So we tested it with another brand new DVD , which was tested earlier with no problems on another manufacturer DVD player. On ours...same problem.     Thus, from other reviews and from my contact with Samsung (who do not fully honour the warrenty), it would seem this one to be a dud. I should have realized a problem when neither model came with a mail-in warrenty registration card, and the information in the manual had a VOID stamp all over it.<br />BUYER BEWARE on this one!
