What best DVD-R or DVD+R?
=========================
The DVD-R format was developed by Pioneer in 1997 vc DVD+R in 2002 by Sony.
DVD+R format was not an official DVD format until January 25, 2008.
DVD-R(W) and DVD+R(W) format are incompatible.
DVD-R(W) use amplitude modulation, DVD+R(W) use phase modulation, so more reliable.
On multi-session DVD-R(W) disk any session take up to 96 MB in time on DVD+R(W)
every session take exactly 2 MB.
DVD+R(W) win!

$ setup.exe -p cdrkit,wodim,genisoimage
Make iso image::
$ genisoimage -A "<info>" -gui -J -R -o <img-file> <dir1> <dir2> ...
<info> is up to 128 bytes. -J adds Joliet directory records wich useful on
Windows. -R adds the Rock Ridge protocol.
To test your image mount it (on Linux)::
$ sudo mount -t iso9660 -o loop,ro <img-file> <mnt-point>
