Unable to burn at 4x using cdrecord and dvd+rw-tools
I have a small problem with my dvd recorder. It's a NEC ND-1300A (dual
format). It writes DVD+/-R at 4x, DVD-RW at 2x and DVD+RW at 2.4x.
cdrecord (either from cdrtools or ProDVD) reports that the drive can
write at most at 2x:

It refuse to work at 4x (with 4x media of course) even using -force.
dvd+rw-tools shows the same behaviour. I also tried cdrecord + Warly's
(firstname.lastname@example.org) patch without success. dvd+rw-mediainfo says:

The media is indeed 4x capable and it seems that the drive knows this.
OS is linux 2.6.3, with glibc 2.3.2. I tried both dev=ATAPI:0,0,0 and
dev=/dev/hdc. Oh, the drive does work at 4x under Windows.
Any clue of what's going on?
