Unspecified target error with DVD-R's (SOHW-832S)

[groovemaster1]

Windows ME
128MB SDRAM
20GB HDD
GF4 MX440 PCI
Liteon DVD±RW Sohw 832S VSOE
Liteon DVD SOHD 167T external USB
Dell 2100
Nero 6.601
Roxio Platinum 6
Clone CD 5.042
DVD shrink 3.2

The DVDRW burns +R’s fine but cannot burn any DVD-R disc. It starts to burn lead in & sticks there until it finally gives up & ejects the disc… ‘unspecified target error…’ The drive has a big DVD+Rewritable & DVD+R DL logo, but says on the box, DVD+/-R/RW

What’s causing this problem???

[please]

@ groovemaster
This problem could be caused by poor media or conflicts with other burning software. You could try removing your Roxio stuff, then running the nero registry checker and driver clean tool. If that doesn’t work, try some better media.
