I tried 2.6.8.1-mm1 ASAP and DVD+/-RW works very well.
I even used two drives together (a CD writer and a DVD writer).

Compiling kernel (using 2.6.8.1 + Petero Patch, cd not used) I got this
error using mkinitrd

I got some error using cdrwtool (it seems to send an ABORT, perhaps
cause it expect that recorder write at 12x ?? I have a 2x CD
rewriter...). I don't know it this information it's useful
