6 disc stock changer in glove box. Played all burnt and regular cds fine and still does now all of a sudden it won't work with any new cd's i burnt. Same burn method and discs and everything. Just skips right over the new ones like they aren't loaded (they are and properly) but keeps playing any other ones I've burnt (in the past) and I can still load those in and they play fine too.. What could be wrong?
