Newbie questions (dual layer DVD with UDF)

  Hi All!

I would like to use my DVDRAM device with UDF packet writing.

System info:

dybs1 /root# uname -a
Linux dybs1 2.6.11.4-21.7-default #1 Thu Jun 2 14:23:14 UTC 2005 i686 
i686 i386 GNU/Linux

It is a SuSe 9.3 system.

Hardware info:

LG 4120B DVD drive on /dev/hdb

This unit was produced about one year ago, it was the first dual-layer 
dvd drive from LG.

I tried to format the disc. 

dybs1 /home/nagylzs# dvd+rw-format -blank /dev/hdb
* DVD??RW/-RAM format utility by <[email protected]>, version 4.10.
* 4.7GB DVD-RW media in Sequential mode detected.
* blanking \

I do not get an error, but this program finishes within 2 seconds. Is 
this normal? Usually it took a minute to format a CDRW disc on my old 
CDRW drive.

I have 'mkudffs' and other programs installed but I really don't know 
how to start.
Do you know a URL with step-by-step instructions?

Thanks,

   Les
