Enabling DMA for atapi cd/dvd/rw

[JD]

# hdparm -d1 /dev/sr0

/dev/sr0:
  setting using_dma to 1 (on)
  HDIO_SET_DMA failed: Inappropriate ioctl for device
  HDIO_GET_DMA failed: Inappropriate ioctl for device

So, could someone please advise how to enable DMA
for the cd/dvd/rw drive?

It would sure help my aging laptop to play high quality
1080p HD movies.

PS: Keep in mind that ide-scsi emulation is used on all
       modern linux kernels since way back ????
