you can still start two running processes of mpg123. with '&' you can
but a job into background and start the next (in the sense of shell
scripting)

so, try the following:

mpg123 -q file.mpg & mpg123 --wav - file.mpg | tee file.wav | wavp /dev/stdin

this first play the file and suppress the output so it doesn't fill up
your screen. with '&' the job get's into the background, but is still
running. if a program doesn't support this option, redirect the output
to /dev/null. the rest behind the '&' is as you now.

well this is not exactly what you want. i guess you want one instance of
mpg123 to do two jobs at once, but it should work too. if file.mpg is
opened read-only, you shouldn't have problems with the above solution.

if it works', try to put it into a shell script. if you need a tutorial
about this topic, let me know.
