Another hand up in favour of the LDW-401S.
So far, with various brands and several DVD-ROM's and DVD players I have experienced no real writing or playback problems.
It is, to me, a drive that represents value and unexpected quality for the price.
Way back when I queried dhc014 on the matter, he said "it was the drive for him"....
I think it was a wise buy. Its apparent "flexibility" is also somewhat of a drawcard for me.
