from our project. K3b and Nautilus depend on burn programs
which have to be compatible to cdrecord. Like wodim or
our cdrskin.

Congrats.
So it is proven that it was a hardware or system problem.

Given a stuttering system, it is possibly about DMA being not
enabled. This command - executed by the superuser - would tell
about the DMA state of /dev/hdc:
  hdparm -d /dev/hdc

One would eventually activate DMA by
  hdparm -d1 /dev/hdc

I understand Lite-On IHAS120 is attached via SATA and thus
not affected by such problems.

But wodim produced a -scanbus . So it was not an overall
system problem. Only half ill, as it seems.

This would be /dev/hdc (in the second reformed
ATAPI-to-Bus,Lun,Target notation).

Here we have /dev/hdd, i guess.
What about this one ? Is it still built in ?
What do you get from
  hdparm -d /dev/hdd

What happens if you read heavily from a DVD in that drive:
  dd if=/dev/hdd of=/dev/null bs=32K count=1000000


Have a nice day :)
