CD labels on backups

[The True Gohan]

Hey all...ok my question is....is it not a good idea to put cd labels on the dc backups? Eversince I put them on my backups...they seem to stop loading somewhere in the middle of the game. I know it's not my dc....cause my originals still work fine. So would it be a good idea just to make another copy from the backup and not put a label? Or could it even be the type of cdr I use? Let me know.....thanks
