Hmm... I've seen this on software CDs whose makers have decided that YOU
MAY NOT duplicate them and run off the duplicate keeping the original as
master "just in case". This is the only thing I like about MS - they
don't do this. Yes, we all know what "backup" is used as a euphamism for
- but dammit some of us actually need to make BACKUPS!!! *ARRGGHH*

Calms down.

OK, one solution - depending on what the actual cause is - to invalid
CDs, whether by damage or design (Ok, damage - brain or physical) is to
use cdparanoia to grab audio tracks to wav, mount the iso9660 image and
just copy off the files, then remaster the contents of the directory
to a new iso9660 image and write to a new CD. 

Usually these symptoms are because of disk damage very early in the
unused parts of the iso9660 headers, or so I've gathered.

So what _are_ you trying to copy? It can - sadly - make a big
difference.
