I've also had problems with CD-Rs and CD-RWs on older machines.  I've
found that the "silver" or "gold" colored CD-Rs tend to work better then
the "blue" ones.

ps - Are all of the machines running Linux or some other Unix?  If 
     you're trying to use the disk on a Windows box, you probably 
     want to use the Joliet extensions.  The following file is a 
     set of notes that I wrote for the students in our lab to help 
     them with burning CD-Rs on Linux:
