@Gurm: Have you thought of the possibility that these could be legitimate downloads?
Don't jump the gun here and gie the guy the benefit of the doubt and leave the moderation up to the staff please.
@twistoff2: Since you don't tell us what exactly you downloaded (file formats etc.), it is a bit hard to give a good advice. Furthermore, the technical details of the media you used, the standalone player in question and your burner may be of help too.
It is possible that your standalone player is picky when it comes to media (if it can play backups at all).
Finally, I will assume that these are legitimate downloads. If not, you would be violating forum rules and I am sure you don't want that.
