ok, forgot the most important thing.
describing the problem....
here is how it is...
normally i place the cd in and then it starts turning, i get a message 'reading table if contents' for about 1-2 seconds then i get something like Albums: 000, files: 000 and after 1-2 it displays the total number of files and albums and then it starts playing.
now, on some cd-s, the cd starts turning, and i hear some clicks that are caused by the lance mooving and touching the bottom of it's housing. it does this a few times. at each click the rotating speed is increased, then it decreases. the clicks are about one per second.
then after about 5-8 clicks i get a message, STOP READ ERROR
