Doesn't starting the player with the `-s-' option do that? I think other folks talked about that here before, but it's not listed in the ``Player Command Line Arguments'' section of the Player App section of Developer Info on riocar.org.

If so, then moving the player app to a different file and replacing the original filename with a script like:

#!/bin/sh

player.new -s- "$@"

should do the trick, I think (read the postscript below).

Edit: It's "-s-", not "-s" (fixed it above), and, apparently, my idea doesn't work. Check out this thread.
