=== [[UDF]] / DIRECTCD / packet writting===

The UDF filesystem is based on the ISO/IEC 13346 standard, now ECMA-167

  mount -t udf -o rw /dev/scd0  /mnt/tmp
  mount: block device /dev/scd0 is write-protected, mounting read-only

  zcat /proc/config.gz | grep UDF
  CONFIG_UDF_FS=m

CONFIG_UDF_FS:
This is the new file system used on some CD-ROMs and DVDs.

Say Y if you intend to mount DVD discs or CDRW's written in packet mode, or                                                   if written to by other UDF utilities, such as DirectCD.

  ...
  Write support requires a block driver which supports writing.
  The current scsi and ide cdrom drivers do not support writing.

=== CDROM===
K3b is a cdrecorder (like windows' nero burning rom)
how to make is usable for users (not looged as root) ?
how to get blank CDROM exact size ?
what about overburnin ?
I heard that it is possible to store data as a single stream ?

To burn .bin/.cue files
