BenQ QScan: only for Win?

Hi to all.
I have a Benq DW1640 on a WinXP computer.
I’d like to put it on an external case, to use it with my iBook as well.
Unfortunately, the QScan software is for windows only, but I need it because I scan every DVD before burning, to be sure to use the correct speed.

Is there an alternative for Mac OS X? is it possible to (effectively) contact BenQ? I asked them but I had no response at all.

Thank you

I forgot to say that I also asked for the specs needed to write myself a program.

Are those specs so secret?!?!
Or am I making some obvious mistake?
