+# usage:
+# first parameter must be %DIR%/%FILE% of the recording
+# second parameter must be the desired base name of the output
+# third parameter must be %CHANID% if you set USECUTLIST=Y
+# fourth parameter must be %STARTTIME% if you set USECUTLIST=Y
+# fifth parameter must be %JOBID% for the User Job status to be updated in MythTV
+# in the mythtv setup screen invoke this script like this:
