No, it wasn't the problem of getting them from the CD. I use tosha to get them.

I wrote the first CD with -T. I'd like to write it without -N but mkisofs gave me no chance...:-( By omitting -N would answer your questions. In this case they would be numbered and the newest one is the one with the higher index. > Anyone with any ideas on this ? > > Anyway ..
