Comment(by anonymous):

 I added one last revision of the patch to fix some sql query issues with
 the datadirect program table update code.

  1. originalairdate may be NULL, and thus the null-safe comparison
 operator (<=>) should be used.
  2. The bit shift for the audioprop comparison was oriented in the wrong
 direction.
  3. A few extra WHERE clauses to deal with situations where the dd_genre
 table does not have any information about a program in dd_v_program.

 After this patch I got one days worth of program table updates down from
 406 changes to just two row changes I can't work around. The two changes
 were due to marking programs as the first part of a multiple part series.
 I can't think of a good way to get around having to update such rows on
 every mythfilldatabase run.

 These last changes were nagging at me because I thought 406/~2000 programs
 per day being updated on each mythfilldatabase run wasn't as good as it
 should be. Now that it's down to just a few programs that are marked
 specially due to their part numbers in a series I believe this patch is
 functionally correct. Only regression testing should need to be done at
 this point.
