I don't know what else to do, it is impossible for me to burn a cd in
dao mode.
It starts burning but stops before finishing (sometimes around 20%, but
depends on what i'm burning).

I se a really strange behaviour: burning at 40x spped, it starts
burning really at 40x, when normally - at least with my cd burner,
under windows (nero) or linux (with cdrecord on tao or raw mode) - it
starts at ~15X and steps 2 or 3 times and ends recording at ~40X.
I post below the output of cdrecord...
Another question: I think I know the differences between dao and tao,
but what is raw mode?
