“Do not display media links” setting has no effect

In the “Website Display” settings for an individual episode post, checking the “Do not display media links” box does not seem to have an effect on the resulting post display.

From what I can tell there’s a problem saving the value to post meta, as reloading the editor screen after checking and saving yields an unchecked box, and examining the value of the “enclosure” post meta for the post in the database shows that field is not set (though the “no_player” setting is working fine).

Could you take a look? Let me know if you need any other info. Thank you.
