# process_dvr_output - a script processing dvr steering + data files

     # This script determines the number of streams opened by the dvr software
     # and creates one single dvrs- and html-file which allow the dvr-plugin
     # to display all streams in one sequence.

     # Last changes:
     # 16/03/09 - Siggi - Generating the first version
