DVDR824DP // DVDRW824K/40 Firmware, help

i recently updated my firmware to P3.4 from P3.3 and now i cannot burn discs at all, the reason for update was that the LEAD OUT didn’t work properly, so the last file that got burnt got damaged… maybe someone knows what might occur that?
and i am also wondering if someone got the P3.0 and/or the P3.3 firmware for the burner, since it’s not available to download from philips homepage
help me, please :o

hmm… do anyone know where i might get it then??
