cdrskin (i am its author):
  http://scdbackup.sourceforge.net/cdrskin_eng.html
Source tarball
  http://scdbackup.sourceforge.net/cdrskin-0.4.2.pl00.tar.gz
Installation instructions:
  http://scdbackup.sourceforge.net/README_cdrskin
32-bit static x86 binary (if suitable for you):
  http://scdbackup.sourceforge.net/cdrskin_0.4.2.pl00-x86-suse9_0-static.tar.gz  As Debian package i would recommend
  http://packages.debian.org/sid/cdrskin (What Debian classifies as "stable" is heavily outdated
and can only burn CD. 0.4.2 is the most stable cdrskin.
Needed for DVD+R is at least cdrskin-0.3.6.)


Have a nice day :)

Ok, so now with a compile of http://scdbackup.sourceforge.net/cdrskin-0.4.2.pl00.tar.gz and an "ldconfig" ;) things are running!

Looks Great ! TAO was executed.

I find this very interesting! The original post noted that only SAO was supported:
Supported modes: PACKET SAO LAYER_JUMP
so I suspect SAO was used instead, as other software might do. That's not a complaint, just a note on something which puzzles me. I would expect the program to note using SAO in place of TAO with verbose selected.

Thomas, perhaps you can clarify the SAO vs. TAO options and actual difference in the media. I assume that a session with a single track will be the same in either mode, but I don't claim to be an expert, only that I'm familiar with the concepts.

Awesome! However, now I have a new problem. There is nothing on the disk? I can mount it, but there is nothing there. To touble check and make sure my track_01.iso was ok, I mounted it too:

mount -o loop track_01.iso /media/cdrom0

track_01.iso was ok. So now I'm tempted to burn another track and close it for S&Gs since the -msinfo worked, and cdrecord automatically closed the disc but I could mount and read it. Or maybe there is something else. So I'm throwing this out hear for direction.

BTW, I will use a new DVD+R everytime, of course (^_-)
