Dvd not writing (LG GH22NP)

[qanda]This thread is about the LG GH22NP. Click here to see full specs[/qanda]hope that am putting this it the right place :rolleyes:

never change any dvd writer over so. this is my first try and yes it’s gone wrong?my problem is that i had 2 sony dvd writers and they packed in writing dvds. got me 2 new LG-GH22NP20 ones and put them in my pc. one as master and one as slave. now they both show up in the bios as they should ?
and they show up in vista as what they are. they play dvd’s and cd’s on my pc. now the old writers showed up as ide ones and the new ones show up as ATA. but nero will not show them or any other writing software.they came as OEM. so downloaded the firmware from LG. but when it try to use it say’s

VALID ATAPI DEVICE CAN NOT BE FOUND F/W MODEL IS DVD-RAM GH22NP20. on the writers it says the same number and made by LG. any help would be more then great thanks
