I'm a newbie ... For a party next week, I try to use mplayer and xmms in
the same time. I would like to project concert video (ripped files in
qvi) and change sometimes with mp3 music files.
But when I ran mplayer and xmms in same times, I can't play files ,
because one of the software (the last run) refused to play, because it
can use audio card ...
So, how can I do this without to run only 1 application ? I have not try
but I think it would be the same problem if I want to use also a
microphone ...

thanks a lot
