To test:
1) Make sure that you have not added an "All Videos" option or a
config.coded_value_map with ID=1738 to the system you are testing
on.
2) Run the upgrade script, including the reingest.
3) Open the OPAC.
4) Perform a basic search using Format="All Videos".
5) Make sure that all the videos you expect show up, and no non-videos
   appear in the results.
6) Try building the database from scratch, using the seed data from this
   branch
7) Repeat steps 3-5.
