+ A lot of what is put here really is applicable to reporting
+ problems and troubleshooting in vlc and the concepts really
+ apply to any sort of bug reporting.
+
+ When reporting a problem it's helpful to have facts:
+
+ a) the version of vlc) you are using
+
+ b) the OS you are running on
+
+ c) the version of libcdio and/or libcddb you are using
+ versions of libcdio and libcddb can be obtained by running
+ pkg-config --modversion libcdio
+ pkg-config --modversion libcddb
+
+ d) what you input or requested (e.g. the full command line entered -
+ if it is possible to reproduce the problem by giving a
+ commandline that is desirable since it is probably the simplest
+ way to convey exactly what was requested)
+
+ People often give (some part) of an error message neglecting
+ to also include what was requested or entered that led to the
+ output.
+
+ e) The setting for this plugin. That is the values of the
+ variables that start cddax- listed above. On Unix this can
+ generally be found in ~/.vlc/vlcrc
+
+ f) Exactly the messages that were what given. You can turn
+ increase the verbosity level by setting "verbosity=2" in the
+ vlc preferences files. On Unix the preferences file is
+ generally in ~/vlc/.vlcrc but there are GUI ways to set this
+ too. Give everything that is in the message log.

+ Get and send a stack trace.
+
+ In addition to -1. Make sure the program has been compiled with
+ debugging symbols put into the code. This is usually done by having
+ the "-g" flag set when compiling the program.
+
+ You can get a strack trace the GNU debugger using the "where"
+ command. For example on this might work:
+

When you run the vlc GUI, under Settings/Preferences you should see
a "plugins" expandable list and under that another "access" list do

of preference. An important selection is "cddax-device." If this is
set to the empty string, CDDAX will try to scan your drives for a
suitable device if the driver has the capability to scan for
rather than /dev/cdrom.

no track, you should see in the playlist a list of tracks on the CD.

The tool cd-read from libcdio can be used to show the sectors of
the CD or CD image or extract sectors.
