So here's the deal..

I've been copying my cd's to my MacBook but I've noticed that iTunes often rips only parts of songs. The computer is doing nothing else while ripping the cd and still it skips the last 30 seconds in track 5 when there's 12 tracks total and it keeps on going like nothing happened.
It makes no sense to me at all.. I can't tell wether it's iTunes fault or my MacBook who can't read a simple cd properly.

I'm using iTunes version 7.6.1 (9)

Anybody experienced the same?
