To my knowledge, you cannot run two userland apps streaming from the frontend at the same time. Generally, when people need to do this sort of thing they write a userland daemon that multiplexes. Alternatively, you can cat the frontend to disk and then have both mplayer and your cc parser reading the resulting file. Devin -- Devin J.
