TV Live vs TV Hub

Hi all, my first post and hopefully a couple of very basic questions to start with.

I now have a WD TV live, which is replacing my older Tvix M6000 media player.

My TV live is a vanilla unit running the latest WD official firmware. I like the look of the themes on these forums, but am slightly confused as to whether there ism a difference to the themes for the TV Live vs the TV Hub ? Most of the themes I’ve looked at seem to refer to the TV hub (unless I’m in the wrong location), so will these work OK on the TV Live as well please ?

Secondly, I have over 500 movies on my Readynas NAS drive which all stream perfectly both through the TVix and the TV Live over a Gigabit wired network connection. All the movies have “movie art” created for them for the Tvix using a program called TVIXIE, which creates a background file for each movie as a file “background.jpg”. Is it possible to utilise these background images on the TV Live, so save having to recreate all of them again with a different package ?

For information, all my movies reside in one of 12 genre folders - Action, Drama, Box Sets etc, and each movies within those genres resides in its own folder called the movie name (and the TVIXIE artwork goes into each of these movie folders).

Thanks in advance for helping a newbie out.

Some themes work and some others don’t. Those that do specy if they do, and usually are separate downloads. For the covers… Most people here use Thumbgen, so if the files are compatible I don’t see why not.
