Now THAT is interesting, because when I look in System Profiler, it says I
have the same drive mechanism as you, but what it says for DVD writing is as
follows:

(no +R DL). I¹ll buy the type of disk you suggest and see what happens.

Is it possible that firmware to permit burning in dual layer format was
added in Leopard? (my MacBook Pro is still at 10.4.1).

Thanks so much,
