problem copying music disks

[Buzzard]

I've just updated my Clone cd to ver4 , i can copy data disks fine, if a little slower than normal, my problem is that when i back up my rather old pink floyd cd's they seem to copy ok, they work fine on the PC but when i try to play them on the stereo they suddenly stop playing at certain places now i did not have this problem on the old ver of Clone CD so my question is what am i doing wrong, i've looked in Clone CD settings and there is only one setting for music CD's
