Query: You have to be lucky

It seems some persons are lucky and receive the noiseless version, this problem si not only with the S321 it happens with other Samsung models too. I opened the player and found that the problem is that the DVD wobles up/down hitting the lens and producing the horrible sound that varies the pitch depending on the part of the movie you are at, I have found no way of fixing it. If you, for some strange reason want to get this player, try it in the shop before leaving to make sure it doesnt make "the noise"
