Basic conditional for TV Shows

I'm wondering what's the standard way for having a DialogVideoInfo that adjusts to whether the container is a Movie or a TV Show. I'm thinking it'd be something along the lines of having two major groups within the file, one with a <visible></visible> that appears if it's a movie, and one that appears if it's a TV episode. I don't know how to refer to that though.

I'm also interested on a conditional that appears only if the container doesn't have a plot.
