Nice work as usual Jezz. It's super-fast, really clean & professional looking and has just a great overall look.
A couple ideas/thoughts I'd like to throw out there -
1. In the movies, would you consider adding the MPAA ratings? I think they would fit fine if you added it at the bottom next to the codec flags. It could be the last one and you could do color-coding of the ratings.
R/NC-17=Red, PG-13=Yellow, PG=Blue & G=Green. Of course, these could be adjusted for the different country rating codes and even the TV ratings.
2. I like the minimal amount of data in the movies, but the one thing I do really miss (besides the ratings), is the runtime of the individual movie.
3. I know it might not be in your vision of the skin, but would you consider adding in an option to hide the sub-menus above regular menu items. Either like a kiosk mode or hidden until pushed up? I like the look of it now, but I know there are probably quite a few of us that don't want some of those areas accessed by the rest of the family.
