Actually, I may have figured it out. Is there a better way to do this?
I don't see why you need the dvds table when the dvd_id is in the scene table:
SELECT a.dvd_id
FROM scenes_list a, moviefiles b
WHERE a.scene_id = b.scene_id

There are a bunch of other columns in all these tables. A quick reason is
need the dvd.title too therefore the dvd table is needed. Another reason is
that the query is generated programmatically based upon parameters passed to
a method. But yes, I do she your point and maybe I can refactor some

by DVD and throwing away the ones that have no scenes. If you start
with DVDs and do a subquery for each row, you'll process DVDs without
scenes and then filter them out. If you start with a subquery that's
grouped by DVD ID,
