Am very disappointed with both the unit and Samsung service. The unit started rejecting all discs...no matter what format...after only two weeks. Samsung service insisted that I try a cleaning disc before they do anything. They couldn't understand that the unit was rejecting ALL discs.After another two calls it took a full week to get authorization to send it out for repair. The unit has been sitting at their designated repair facility for two weeks now "waiting for parts". No one can tell me what is specifically wrong and Samsung will not just replace the unit.I can only say this is a very bad Samsung experience.
