Cd burning problem

I have burned different cds using different software. I get a problem playing those cd that I burn. Presently I use eproformance 32x cd r. When I try to play these cd it plays fine until track 7, these rest of tracks plays but skips and plays.

I do not put a lot of tracks on the cd, they verage about 15 tracks per disk. The size of the disk when burned is between 550 mb and 620mb. The playtime is usually 10 minutes less than the cd is capable of holding.

Can anyone give me an idea as to what causes this problem. I have also changed cd writers, but it still burns the same way. I tried another brand of cd and still I get the problem. For every 15 cd i burn, one would play fine and the others I get this proble.

Any advice?
