Please Help!! Burned cd's have static on playback

I've been trying to burn cds from my itunes and when I go to play them back at about song 8 the songs have static and will start to fade in and out and will eventually stop playing. The first few songs are perfectly fine. I don't know what could be happening that would cause static to start halfway through the burned cd. I've tried changing my preferences to AIFF and Apple Lossless, but this hasn't been helping. I am getting very frustrated. What else can I do to get a decent burned cd??
