#TODO: 
# * run the media player inside an xterm on the new screen so that
#   console output is available
# * run an xterm in the new screen anyway so you can do some diagnosis if you
#   need!
# * should this script be SUID root with only the startx command being run as
#   the real user? over-reliance on sudo is a little disconcerting.

#what's your favourite player?

#Start xine in fullsreen mode and use the slow but failsafe Xshm driver

#FIXME: this is ugly shell scripting at its best, but it is also 
#incompatible between xine and mplayer :(
