I have a wordpress 3.5 cz. I plug in version 1.6.8.3 While creating a new category, but I can not assign it to a function like this on video. I only have the Basic version, but that’s probably not the problem. And one more thing, do not work Czech characters. And yet in the older version are going fine.
