Audio Systems: matrix cd player ejects cds, alignment problem, toyota matrix

Question
I have a 2003 Toyota Matrix.  The cd player recently started ejecting the cd almost every time I insert it.  After many attempts it sometimes plays it for a while.  I have tried an automobile cd cleaning disk and I still have problem.  Do you think it's an alignment problem.  What would you recommend for repair or replacement.  I live in the Annapolis, MD area.

Answer
the disc are eject when the  disc is dirty or the laser is dirty  
if there are more than 3 errors when playing the cd is remove by the bad information
you need to clean the cds and open the radio to clean the laser eye with a q-tip and alcohol there is no nother way it will work again
good luck
