Re: query about optical disc format

I am running Debian 6 on this computer.

In trying to find what happens with a DVD that is written from a DVD
recorder /player and television tuner, I put the DVD in the computer
optical drive.

The computer did not automatically load any DVD/CD application, to play
or do anything else with the disc, and the File Browser utility does not
see the disc.

In looking around in the menu's, I found, in the Applications -> System
Tools menu, "Disk Utility", and, in running that, and selecting "CD/DVD
Drive", I found that, under "Volumes", it has:

1.0GB udf

Usage: Filesystem
Type: Universal Disk Format

Does an application exist for Debian 6, that allows access to these
discs, and, that allows users to view the recorced video files, on a
computer running Debian 6?

apt-cache search video |grep DVD |less

Whilst the open/close button on the drive, does not allow me to eject
the disc, until I use the Disk Utility option to "Unmount the media",
apparently, all that I can do with the disc, is insert it, using the
Open/Close physical button on the drive, and then unmount the disk, top
eject it, but I apparently, cannot read the disc.

~# man eject

Looking in Synaptic (searching on "universal disk format"), returns
three results, and the closest, most applicable result, seems to be the
package udftools, which has the package description

tools for UDF filesystems and DVD/CD-R(W) drives

This package contains a number of user-space tools related to
creating filesystems in the UDF (Universal Disk Format), which is
primarily used for DVDs, but sometimes also CD-ROMs:

mkudffs - Format a device, creating an empty UDF filesystem
cdrwtool - Low-level drive management (e.g. set writing speed, format)
pktsetup - Set up a packet writing device (/dev/pktcdvd0) for a drive
wrudf - Maintains a UDF filesystem (undocumented)

So, whilst a utility appears to exist, for creatung a UDF filesystem,
for Debian 6, apparently, UDF files and UDF fylkesystems cannot be read
by Debian 6.                                ^^^^^^^ file not fylke

Is this correct?

No.  Install the udftools package.
Then do
less /usr/share/doc/udftools/README.Debian.gz which explains how to get UDF working.

Thank you in anticipation.

Your welcome
