Jjeff suggested cleaning the hub/spindle on the DVD drive. This is described in detail here:

Procedures for removing the DVD drive lid may vary according to the design of the DVD drive and machine.

If the DVD drive has the black plastic case (2005 and older models) the top cover is anchored at the rear and lifts from the front. In this case it may require removal of the machine's front panel to give enough clearance to lift the drive lid at the front and slide it forward allowing disengagement at the rear. (On a model with a VHS drive be sure to hold the VHS door open as it's being fitted back to the case. This will correctly align the VHS door lifting mechanism.)

If the DVD drive has the metal case (2006 and newer models) the top cover is anchored at the front and lifts from the rear. The machine's front panel doesn't have to be disturbed in this arrangement.

Pay special attention to the positioning of the roller assembly at the rear of the disc tray. Upon reassembly it has to be in the correct position to align with the guide rail on the underside of the DVD drive lid.
