I wanted to provide a viewpoint of that of the novice individual. When i first tried out MediaPortal skins were first on my list of things to look for. I tried varying skins but I found StreamedMP one of the simplest to get up and running like the screen shots show. Plus Ltfearme and the others work with plugin developers so there skins work in my opinion near flawless.
I have been a fan for over 18 months and will continue to use this package until... well forever :)
