Yes.  The path was set up correctly.  I have no idea why it could find 
some programs and not others in /bin.

My sister said her employer has also had problems with blank CDs and 
DVDs.  After trying a number of venders, she said that they have the 
best luck with Maxell.  97% I think.

I think my CD writer is pretty good. It's a Plextor SCSI drive.

Even if I manage to solve all of the problems, this would be a good

about ramdisks, initrd, and loop devices.

I'll put a message out to CLUE and see if anyone has some answers.
