What do you mean? There's only one executable 'mplayer' and only one 'sudo'.
I also added /usr/bin/id to the list of commands I can run as root, and it
printed "uid=0(root) gid=0(root) groups=0(root)" - same as after `su`. So
just don't see where in theory the difference in behaviour could come from.

P.S. Let's exclude the possibility that the program checks for $SUDO_UID and
refuses to run on purpose.
