PLDS DH-16ABS Software from Liteon

      I'd given up on finding anything for this DVD-RW, and stumbled into this...from liteon which makes sense since they made this thing to begin with.

Anyway, there is EZDub which is basically just software to help you run the drive which they call EZDUB 

And there is actually a small, free utility they have made that automatically checks your optical drive and then updates your firmware.  It is called: SmartPack.  They can both be On This Page found 

Spoiler Alert!  Smartpack won't find firmware for it because, as someone has mentioned, it doesn't exist but should they ever decide to create firmware for this drive it should be easy to get to.
