Optical drive problem - TiBook

[Łukasz Studziński]

I have a problem with TiBook 667MHz - built-in DVD/CDRW seems to be ok
(it is seen by the system), but I cannot put any disc in it. I can put
adisk inside to the moment when a hole touches an edge of the computer.
Then I feel resistance - I cannot push even a milimeter more (in fact I
did not try too much because I was afraid that I can destroy something).
I wonder if this is hardware or software issue.
