growisofs minus_rw_quickgrow question

["chen zhao" <dinningc@hotmail.com>]

Hello,

   I was trying to write arbitrary files to DVD-RW using growisofs.  When I 
use
	dumpsomething | growisofs -use-the-force-luke=seek:N -Z /dev/dvd=/dev/fd/0, 
the DVD can not be play back. I think it was because the media wasn't 
closed, but I don't know how to set "quickgrown=1" to active "Close session" 
cmd in minus_rw_finalize. So, I checked the minus_rw_quickgrow function, and 
get confused. Can Andy or anyone please explain how can type ==2 be true 
when format was not initialized?

type = format[4+4]&3

   If I just add quickgrown=1, what will happen?

Thanks, Chen
