view element of field array empty - unable to display embedded video

Issue Summary

Hi - extremely perplexed with this one....

I have 3 custom content types that use the embedded video field. All three share the same field. The first 2 work fine and display video (and audio) with no problems.

The 3rd, which is the most recently created type, does not display the media.

When outputting the contents of the $node array using dpm($node), I can see that although the 'embed', 'value' and 'provider' elements are all populated, the 'view' element (which provides the html to output the embedded media using the emf module) is empty!!!

I've attached screenshots from a healthy node (withview.jpg) and one from the latest node with the empty view element (noview.jpg).

I've checked permissions on the CCK field, which are fine as it is re-used in other functioning content types, but I am at a loss to understand why the view element is empty.

Can anyone help with this?

Thanks
