The template you are using is the Default Thumbgen template for “Movies”
You will need to edit the template tokens for TV Shows …eg.
%TITLE% is used for Movies
%PLOT% is used for Movies
%EPISODETITLE% is used for TV Shows
%EPISODEPLOT% is used for TV Shows
here is the documentation of TV Show tags / tokens that you will need to edit the template
Also, if you plan on using the Default Thumbgen Moviesheet … then you will have to do some theme edits, otherwise the Movie Info and the XML file info will be jumbled together. (as you found, trying to use it with Tinwarbles Mojo Theme)
