Music Won't Burn To Disk Correctly

i have windows 7 home premium,4gb ram,comletely updated. i am using windows media player to burn music to a cd-r disk which i have always done in the past.only difference is now im using a 52x instead of a 40x.i dont know if this is the problem or not.all the songs im burning are in mp3 format. when i burn all the songs to a 52x cd-r ,the first 10 or so songs play fine when i play then in my truck in my cd player.after that,it takes multiple passes of the cd player to find each individual song after that.it makes a skipping sound as though its searching for it or it cant find it or read the disk.at times it will even eject the cd and say there was an error reading the disk.i tried different setting through windows media player,including dropping it down to a 20x,slowing it down,using wav format..etc.still nothing.when using the 40x cd-r,it will play almost every song in my truck without hesitation,except for the last one or 2 songs.the songs all play fine through my media player after they are burned,however,once i put the cd-r in my drive,i go to C: and look at my drive where the cd-r is located,its showing that there is nothing on it,that there is 0 used on disk.if i double click the drive,it gives me this error....this file does not have an program associated with it for performing this action.please install a program or,if one is allready installed,create an association in the default programs in control panel.basically i cant open the file by double clicking on the drive,but if i right click my drive and click "open"..it opens..lol..so confusing.never had that problem.will even open in any player i want,funny thing is it show nothing on disk when i look at my drive.all i really care about is why i cant burn these correctly to cd,and that it only burns thah first 10 and and the player has a hard time burning the rest?
