thanks Ziyad, I never imagined that computers could rip Cd's so fast !
If I understand you well, it seems that DMA is not quite working out of
the box then, in Ubuntu. Well, as I said, it more of an academic
question, as I don't have any CD to rip anymore, and the only DVD I
have, I rarely watch it.
I will give ripping another try, in 3 months, when Breezy is released,
purely out of curiosity.
