Hi There, It seems more often than not when I put a DvD in the player to watch the player is not recognising the DvD and when it does it quite often gets part way through the DvD then goes back to the beginning! Any Ideas if this is a common problem and what the solution might be? Does it need cleaning? Not sure what the simplest method of doing this is? All the DvD's I'm using are original films and although the problem improves after cleaning the DvD's it still remains for many of them.. Any Help appreciated.
