Looks like your driver doesn't use /dev/video0, or does it use any other file? But, why do you need to do the above using root?
I am assuming you are running the above from a terminal on the X server. By default all display options to root are disabled. Open a terminal as a user on the GUI, and do:
xhost +
Then su to root:
su -
Password: <enter root password>
Now try with mplayer.

#xhost +
access control disabled, clients can connect from any host
Ok, now access is enabled.
After su to root, see what is in:
echo $DISPLAY
If nothing is set, use:
export DISPLAY=:0.0
I'd also recommend asking in the mplayer users mailing list. The developers are there and will give you a more appropriate answer.
