If you send your player to the German external service partner "Teleplan" I can completely understand your opinion on Samsung's service. Teleplan is responsible at least for computer monitors, and they are horrible. You often have to wait several months without any reaction from them before you get your monitor backl. I had to wait 2 months for my Syncmaster to come back completely covered with some smeary oil-like fluid (not only on the chassis but also on the TFT panel!) so that my first action was to clean it.
If they behave the same for MP3 players, I can't think of a worse service. I don't know why Samsung keeps sticking to them...
