How do I load themes and moviesheets on the Gen3 WD TV Live?

I tried downloading themes and installing however it doesn’t seem to load.

Tinwarble’s instuctions on how to install Darklight are very explicit and could be useful for whatver theme you are installing on an SMP, though Darklight would be a great choice. Highlighted on the page in purple is the specifics for installing a theme on an SMP.

Darklight for SMP
