Yes; the choice is in setup under skins I think.
No, it wasn't under setup->skin. this don't exist, maybe "appearance"?
But i tried all those and it didn't change back to the old lay-out.
What i did find was the red button on the remote control this change the view back how it was.
But you need todo this for every movie, every folder, every episode.
My server is huge(24TB) and i have thousands of movies that's why i need a simple layout.
I don't think they want you to use the old lay-out anymore (they made a lot of effort to change it).
but we can always go back and forget this "crappy" firmware :-)
