Macbook Pro with some problems

[NGokal]

I have a macbook pro 13" (mid 2009) edition. I bought it couples months before the new macbook pros came out with the i3,i5 well I been having problems with it. My first problem was when i got it and then 2 months later I had a burn mark on the screen well i got that fixed, then couples month or so later my dual layers wont work and i got that fixed, well this time my dual layers wont burn again. So my main question is that does apple have some kind of policy or something that if you have a certain amount of problems they will make some sort of deal with you like a new macbook or extend warranty or something? I'm just asking because some computer brands have some kind of deal they will work with you.
