CD player won't play CDs burned on new computer

I have no idea if this is a problem with the CD player itself, but all the CDs I burned previously on the old computers running Windows 98, ME and XP will play in my car cd player. All the CDs I have burned on the new computer running Vista will NOT play - one of them will play but I can't skip ahead;. if I try the player refuses to play the CD anymore. One of them will play about 3 out of the 16 tracks. The rest of them, I just get an ER-7 message. I ran the cleaning disc through the player - and it took about 20 tries inserting and reinserting THAT before it would read it - and still have the same problem.
