They work fine using the device name rather than playing with the ATA or ATAPI stuff. And if you're using ProDVD I suggest you download the latest cdrecord from the usual site and build that, DVD support is now in the cdrecord source, as it is in most distributions. I use multiple PATA and USB burners on several systems, and haven't had problems. I actually do have SCSI devices, they have always worked and continue to (slowly) do so. If you post again after trying the current source, please include the command used as well as the output from the log. By using the latest you at least MIGHT get some help from the author, instead of the usual "don't bother me with obsolete versions" reply.
