Question

I have a 1999 gmc sierra that the cd player won't play my homemade cd's. I replaced the original player with one from a wrecked truck and get the same result. When I put one of my burnt cd's in it kicks it back out and says err. I sometime have to put my regular cd's in the player several times to get them to play. When it plays it sounds fine. I'd appreciate any help I can get on this situation. Thanks, Darren.
