Nec1300a still wont recognize DVD+R after flashing with Herries 1.0C Firmware

I have a NEC 1300a DVD and with the latest official firmware version 1.0b it only recognized the dvd brands listed in de Media List from NEC.

I flashed my drive with the latest Herrie firmware version 1.0c but unfortunateyl it still wont recognize my other DVD+R’s (Arita and Fortis)

When i insert an Arita DVD (Mediacode RICOHJPNR01) the drive tries to read it but after several seconds the green light is switched off and win XP/2000/Nero says there is no media in the dvd.

Anyone got a clue???

if it will read other +R discs, then it probably just doesn’t like those discs
