Hmmm, strange situation. I presume you need samba because you want to
mount stuff from windows machines, right? I have only worked with nfs so
I have no samba experience (can't dance either :-)

Anyway, I would take a look at the optimization of the cdrom itself, to
make sure it is using dma:
  /sbin/hdparm /dev/hdc
If it is not using dma try adding that:
  /sbin/hdparm -d 1 /dev/hdc
(hdc or whatever your configuration is)
See if it makes a difference.
