Well, this has gotten off topic. But to answer your question, first, the SMP/HUB is firmware based not software based and there are no “programs” involved. Second, I don’t know where you would get that it involves any more work to add files to Genre folders or that it is in anyway limiting, since no matter how you structure your files, you still have the same options to search/sort your files (the xml data is still there, so it’s not a limitation).
“As a side note, if you take 1,000 video files and slam them into one folder, vs single folders for each .avi (movie) file, windows loads that main folder a LOT slower and slams your PC trying to generate images and find out the specs on those files.”
No, for one it’s not like a PC, for another, you are already doing basically the same thing (acutally worse, because you are telling the SMP to ignore your folder structure and use a virtual structure) by filtering it to “All”. And when you filter by one Genre you are still doing the same thing as if all the movies in that genre were in one folder, except the SMP actually has to look at every xml file to find that genre you are filtering by. And you are already using what the firmware allows you to do by filtering by “Folder”, so I’m not seeing where you see that it is something other than that. Because, as I stated, no matter how you structure you files the same options are there, even though mine are seperated by genre folders I can still filter by ALL, GENRE, etc., my folder structure does not limit that.
Also, here’s another thing to consider, many people want to sort there movies by whether they are standard def or BD. This is something that can be done via folder filtering, but when you filter by all, genre, etc. they all get dumped together.
To answer your theming question. No, you can’t modify the folder view to suit what you want. This is because there is no way to modify how folders are displayed alone. Folders & files are linked together, so what ever you do for one is what is set for the other. The problem though is not in how the theme xml’s are designed, but with how the firmware handles the varibles and with difference in how it handles folder and files. So there is no way to change that within the theme itself.
But to get back on topic and as it’s been known for along time, you CAN NOT display meta and backdrops for folder. Which was all I was concerned about to begin with.
