I have had this denon dvd2900 since october last year and has perfomed beautufully until yesterday. However, i noticed since yesterday everytime i play a dvd, the dvd rattles continiously and the rattling noise can be heard about 4 metres away with the sound muted or low. Has anyone expereienced this problem before ? The player is still under warranty and i just have to return it to the dealer over the weekend for a repair or swap. Any information will be appreciated. By the way it rattles when playing any dvd's cd's SACD's and even DVD-A!!
