So in theory I could save the TVDB and TMDB a lot of trouble, and perhaps even speed up my library scanning a little, by storing local versions of meta images on my NAS? Cool.

Local artwork will definitely speed up scanning. It will also give you more consistent results as you will be able to select higher quality artwork. In addition, your artwork will always be available should you add another client, whereas internet hosted artwork has a habit of disappearing (this point is important when adding extra clients to a shared library).

Hmmm, wonder if your texturecache script can convert from the cached filenames to real filenames and copy them from cache to my NAS? I suspect it can, time to read the full documentation

No, it can't actually - there's already the built-in library "export" option for that. However, you'll just be exporting your cached artwork, which will contain resized and lower quality versions of the original artwork so it's not really an ideal solution IMHO. You're better off using something like Ember Media Manager to organise your local artwork (using the highest quality available) and metadata.

I was trying to do what popcornmix suggested earlier in this thread here might help speed things up. I lurv speed However it sounds like I was fishing without bait and I can't interpret these results anyway

Here's my results:

Movies

TV

That looks like it's working normally. For Movies, all your posters and fanarts were already cached, so nothing more needed to be cached. However for TV Shows your cache was missing 21 items so they were added to the cache. Now your texture cache should be fully populated and the GUI not wasting any more time encoding artwork as you browse through your movies and tv shows.
