The only difference between these two pictures is the first uses a cube
as the reflective surface, the second uses a plane. Why does the plane
cause the media to not show up?

What reflective surface? Did you try hollow?

Tim, Are you using the 'hollow on' option with the plane?

Nope. Should I?
...how can a plane be hollow? ^_^;

Planes have an inside and an outside. The normal vector points in the
direction of the outside. If your media is essesntailly inside the plane it
won't render, check the message window, it should say something about being
inside non-hollow objects. Either reverse the normal of the plane or, as
other said, add the "hollow" keyword.

Because a plane in POV is not just an infintely thin surface. It has an
outside and an inside. Like in the image below.
^ outside
--|--
/ | \
/ \
-----------
inside
Therefore, if you have media below your plane, you have to add "hollow
on" to your plane definition for it to show up.

I discuss this a little bit on my d10 tutorial at
http://www.hoboes.com/NetLife/POV/Die10/
Planes are solid objects, too, they're just shy about it :*)
