It might be a firmware thing, but I doubt it. I was able to burn all of the media I had before the reformat. I tried DeepBurner, but that just produced coasters. The good news is that I was able to get my unmarked DVD-R media working again in Nero 6. Now it's having problems with my Sony DVD+R and DVD+RW media. The odd thing is that these used to work, on the same firmware.
