Audio MP3's made on Microsoft System 7 PC give 'Focus Error'
 

I have a 2008 Civic Sedan with an AM-FM-CD-MP3 player. It works fine, except new MP3 audio CD's made on my Dell PC with Microsoft System 7 (which I got a few months ago and still hate) all show 'Focus Error' when I try to play them in the car. They play OK on the computer, and all the older CD's (MP3's made with Microsoft XP, commercial WMA's, etc.) still work fine on the Civic player. Obviously the problem is with the System 7 computer-made CD's. Any ideas toward fixing the problem. Thanks.
