# How to add new file options:

# In the class NEWFILE, method CREATE_DEFAULT_VIDEO_PARAMETERS, add the new option
# to the SELF.FILE_PROPERTIES dictionary, setting its default value based in the
# SELF.FILE_VALUES values (the ones obtained with MPLAYER --IDENTIFY), SELF.PAL (True
# for PAL output video, False for NTSC output video) and SELF.DISCTOCREATE (DVD, VCD, SVCD
# CVD or DIVX)

# In the class FILE_PROPERTIES

# In the method GET_WIDGETS, set the parameter value in the SELF.FILE_PROPERTIES
# dictionary using the widget's current value

# In the method SET_WIDGETS, set the widget's value using the parameter value in
# SELF.FILE_PROPERTIES

# If the widget must be disabled or enabled under some circumstances (other widgets)
# set that code in method SET_FILM_BUTTONS
#
# Finally, add the needed code in DEVEDE_LOADSAVE.PY to ensure that old project files
# work fine with the new options
