Problem with NEC 1300

I cant seem to get my NEC 1300A to burn TRAXDATA DVD+R 4X. I cannot understand this since everyone Ive spoken to says that should work fine. Ive tried Flashing my FirmWare to, first, 1.0B and then to 1.0C, but it does not help in any way.
Now: I tried to search around on the Forum, and it seems that Herriere`s Firmware should do the trick…!!! Problem is I cant get the damn site up, and havent found anywhere else to get the hacked Firmware. Could someone PLEASE help me with this?
