[McButton]

I think a "lite" version of Madnox would no longer make it Madnox. There are older Nox versions that look similar, but most of it will be broken and unsupported. Still, this is one of the heaviest skins available. As such, it gives you a ton of options.

If your box allows for some sort of hardware upgrade, you could do that. Otherwise, you can rely on your .nfo files to direct link which will give a "trailer" button" from the internet or don't link to anything and Nox will give you a "search trailer" button.

Since you have a low internal hd, you have to adjust as such to allow for image caches and saved files set by Kodi.

How often must you watch trailers anyway that you need each movie to have them? I have this problem (Chromebox), and general search works great.
