You can use field_language() to figure out which language to use for a
specific field. It will return an array in the form of 'field_name' =>
'language key' ('und' in your case).


I am however not sure where to get the necessary arguments for that
function from, especially entity_type, no idea if you can get it from
the views metadata.
