It sounds like Page A should have posts being listed (dvd_list) and then Page B should be outputting those posts or Post.
But to get a field from another page check out the answer I received from @Hube2 here https://support.advancedcustomfields.com/forums/topic/output-fields-input-through-template-a-to-template-b/
Essentially the_field('field-name', page-id#);
