Your media supports upto 6.1x as shown by your dvd+rw-mediainfo command.
However, if you do "man growisofs" it says that -speed=1 should be used
if higher speeds mess up your media.

Well nevermind, growisofs was using 1.0x only :). But there seems to be
an error for the medium type!

Here it says that your drive has firmware 1.04 installed. The latest
firmware for 3520a (OEM) is 3.05
http://support.necsam.com/OEM/downloads/FlashFirmware/ Upgrading the
firmware may solve the problem if it is due to media.

And the media you are trying to use is a DVD-R as shown by
dvd+rw-mediainfo command.

I hope that helps.
