The concept of this skin is to make all options in MediaPortal available as easy as possible and this in an attractive way. I have tried to maximize the use of fanart but still keep focus on usability. As a user of this skin you can customize the main menu and also what images you want to use for different views in the skin. X-Factor was originally based/built upon the great skin files from StreamedMP.
The idea behind the main menu is to have a menu that fits the area of one screen so you can get a good overview of all available options. Moving to a menu or sub menu changes the backdrop image. The skin have a built in menu editor so that you can edit the menu items (basichome) from within MP Configuration. The skin comes with three different menues that you can alter between within MP.
The skin skin is developed for 1280x720 resolution but thanks to the MediaPortal software it scales beautifully up to 1920x1080.
I have been using the X-Factor skin for over a year now, and it rocks.
The menus are very slick and designed in a way to combine sub-categories of functions. This reduces the clutter and makes navigation far easier (you don't have one very long scroll list, just 5 categories with smaller scroll lists under each category). Configuration requires some fiddling, because there any possible combination of menus is configurable. Some people might see the slightly more complex configuration a negative aspect, but it gives massive flexibility, which is what I want from my HTPC.
It provides good support for all the main plugins along with most of the lesser known ones, and support from Cul8er is excellent.
With the inclusion of the excellent FanArt Handler to provide downloaded fan-art background (also written by Cul8er) it provides a very impressive and fluid look.
I would highly recommend this skin if you want a very professional and hugely configurable skin.
