"Although the current DVD recorders 8X have the necessary energy in their laser beam (30mW), for writting a DVD+R9 disc, nobody can assure that a firmware update is enough for converting them in DVD+R9 writers - and this because the official specifications for the DVD+R9 writers will not be out before the end of December 2003. The sure thing is that the 4X DVD recorders will not be able to write on DVD+R9 discs because of their low energy laser beam."
