No, definitely not, burnfree is a good thing. It prevents buffer
underruns, especially on slow machines. Burnfree is what makes late
model burners so reliable.

It checks the md5 against what is posted on the server you downloaded
from? Or are you saving the file and it checks against it?

It could possibly be the old CD-ROM drive in the target machine can't
read CD-Rs very well as they came after the creation of the drive.
There are audio CD players that are years old that cannot read burned
CDs so I would not be surprised if there are CD-ROMs that don't have the
same problems as well. I don't understand how the speed you burn on the
host machine has anything to do with the read quality on another machine
though...

MMmmmm, Slackware, my first linux love.
