It sounds as though one of the files you're trying to burn might be corrupt. Either that or it has a copyright use that's over it use by no. If you have any cd-rw's experiment either those. OK you'll ony be able to play those disks on your comp or on most of the newer set-top dvd players, but since it is erasible, it is worth experimenting around with until you find what the problem is. Choose a different set of songs or leave one out one by one starting from the 4th one (since that seems to be where the burning process stops!)
