How sad. Apparently, the drive *does* support the play command,
but if there's no place to plug in an audio cable, there's no
way to get sound out of it. And if there's no headphone jack either,
then the analog play function is basically useless. :-(
It reminds me of a quote by my high school chemistry teacher:
"An engineer that can't write reports is like a cow without teats".
cdinfo -v
and
cdir
will also give you a status of what the hardware is doing.
(i.e. whether the device is playing or not, what track is
playing, how many minutes have elapsed on the track, etc.

OK.

True. And it's easier to implement for computers where it's
difficult to access the hardware while the machine is running,
such as in a laptop. But unplugging the cable is very effective
at convincing people!

Uhh ... OK, now I'm confused. You just said that the drive does not
have any analog audio output. So it can't work in analog mode in
*any* PC, right? But you just said you got it to work in analog
mode in another PC! How is that possible? Are we talking about
two different DVD drives? Are you sure that win xp was using
analog mode?

Now I'm even more confused. I don't remember whether my Debian box
uses totem or rhythmbox, but I'm pretty sure that whatever is the
default media player uses the digital playback method.
