#
#Prerequisites
#
#In order to run the encoding scripts, a number of tools, libraries and
#codecs need to be installed.
#
#The video transformation tools are:
#
#    * ffmpeg
#    * mencoder 
#
#The codecs are:
#
#    * libavcodec-extra-52
#    * libaften0 - Not required if you have the license and title AVIs! 
# (for creating the title and license AVI, we needed it to have fake
# silent audio as AC3 to match the AVIs created from the Session MTS
# files, or mencoder would protest) 
#
# To test the results:
#
#    * mplayer
