So I had some trouble deciding if this belonged in software, general discussion, or hardware. But since my cd burning process depends the most on software I thought that it deserved a home here.
So I got a volvo (idk exact year, mid-nineties, '96 maybe?) and it has a stock cd player. I tried burning a music cd and playing it, but it doesn't play. I burn my cds using windows media player....
the car plays regular cds just fine.
But the other night I was at an "outdoors" party, and I was playing music with my car doors open, and someone slipped in a burned cd they had. But it played!

Can anyone think of what might cause their burned cd to play, but not mine?
