| I have a NEC 3500a dual layer DVD burner, and when i try to burn a dvd with dma on it automaticly gives an error, in whatever program cvdrecord.prodvd or growisofs, with dma off it burns but getting average speeds of 2.6x when i write at 4x. Iam using 2.6.9-ck1 kernel with ide-cd. Is there something that iam missing or this is suposed to be like this, because having brougth 8x dvdr media and burning them at 2x is a bad deal. |

Have you tried using other kernel sources than -ck? I also have a NEC 3500A, and it has always worked perfectly. I even burned 2 DVDs at the same time once - one in a NEC 2500A and the other in the 3500A - and they turned out fine. I've used it without problems with both vanilla 2.6.7 and 2.6.9 kernels.
I use K3B (*NOT* KDE, just K3B under fluxbox).
With 2.6.8+ kernels (including 2.6.9) you'll need to be root to burn, unless it has been de-patched - not sure if -ck patchset does that. I use 'sux' under X to run K3B.
Oh, and it's not a bug, it's a feature 
If that's not the problem, I recommend trying the vanilla development-sources, and see if the kernel is the problem. It's definitely not supposed to be like that. |
