I had never tried this. But when I tried just now it is very slow. The
video plays very well under Mplayer but this audio dump is slow.
I however use vsound for converting only sound part from mpeg and rm files.

Description: virtual loopback cable for audio
VSound is sort of like a 'virtual audio loopback cable'. That is, it
allows you to record the output audio stream of a program (similar to connecting
a loopback cable to the line in and line out jacks on the sound card, and
recording the sound from the line in jack, but without the DA/AD conversion
losses). One possible use for this application is as part of a RealAudio to
WAV file converter.

LOST #046 -**< Sub : Console gibberish (#2) >**-
To clear gibberish all over the screen (e.g. after cat of a
compressed or binary file) use "tset" from ncurses-bin package
Usually the command "reset" will clear the screen for you.
"reset" is merely a symlink to the program "tset".
