Its fixed, dont ask how cuz i dunno.
I just played around in the audio settings and tried to burn the cd again and now its fine...without filters or anything.
Anyway thanks for the replies (however everbody seems to think i cant burn mp3's which wasnt the problem
)
Labret, they were someone elses rips but like i thought before, it was a problem in my sound settings somewhere, not a software problem nor a mp3 problem.
