DVD-R "This disc is not writable"

I have a NEC 3520A. It records DVD+R single layer very well. I can’t record any DVD-R media. I get “This disc is not writable” messages. I upgraded the firmware from 1.04 to 3.04 (official versions). No improvement. I have tried three different DVD-R media, at different recording speeds. It still might be bad media, but I don’t think so after three different brands. I’m considering re-flashing with Liggy’s firmware. Any other comments?

Environment:
Win XP SP2
DVD Shrink 3.2
Nero Burning Rom 6.3.0.5
NEC 3520A firmware 3.04

“Bad” Media:
DVD-R Maxel 8x - RitekG05
DVD-R Fuji 8x - ProdiscF01
DVD-R HP 8x - CMC MAG AE1

Again, DVD+R works great. And I have tried recording at slower speeds.
Comments? Suggestions?
