I don't really understand what it is you're trying to do and what goes
wrong? For example, what are you trying to accomplish with sox?

I am a newbie... I just follow the instructions :-) I hope I didn't do
anything wrong.


This is wrong,
 mplayer vcd://<track 03>

It should be,
 mplayer vcd://3

How is mplayer set up on your system, what video output and audio
outputs are selected? Have you done any configuration yourself?

MPlayer is setup the way it came when I got the package (plus libs)
with Synaptic. Unless there was something in the above that you would
call configuration...

The above output seems to indicate that MPlayer tries to use MGA and
then framebuffer for video output, and fails, audio output, with alsa,
also seems to fail.

I would first try this,
 mplayer -vo xv,x11 vcd://3
and see if I get any visible video, and later worry about sound.

Wow, I've got video. No sound, but hey it's a start. I can't get video
with the GUI, however. In GUI I get the following:

"Error opening/initializing the selected video_out (-vo) device."
