SDVD8431 Wont Burn

I’ve got the Philips RW± SDVD8431 for my laptop, with firmware LJ41 , and i recently bought DVD-R’s[Verbatim 16X]. But i can’t burn them!
I can’t seem to find a firmware so i guess there is no other firmware for it.
Anyone knows what the problem is? - Kenn

You could try updating the firmware as its an OEM model there are a few around, this appears to be the newest;
