I got my first dvd writer. It write both cdrom and dvd, something that bother me is that speed for dvd writing is never more than 2x (device and medium are able to do 6x speed) and with cdrom mostly 8x only sometimes it manage to get 16x speed (device is capable of 48x).
My (more modern) hardware shows a similar behaviour. Sorry, I can't find the link right now, but IIRC linux has just some more conservative settings for burning CDs and DVDs than some other OS. The bottom line is that for most (linux) people it is more important to be able to use the burned media in future, than to gain marginally from burning a CD with 48x instead of 8x. Usually the burning quality is inferior if the hardware is pushed to the limit.
Personally, I don't tweak the default settings that come with debian, since I trust they reflect other peoples' experience as to get the best results.
