I just tried this today and had a pretty decent result.
9 out of 10 trailers were spot on.
Couple of things:
I was doing a directory with 100 folders. It got about 90 of the 100 films correct. So I went and deleted the incorrect ones.
Then later, I added a couple more folders to that directory - however to get these to "auto download" I'd have to scrape the entire thing again...which I don't want to do, because then I'd have to delete the wrong ones again.
I was not able to set the path to the film directly, because it was expecting a sub-folder...
My work around was to create a temporary folder, drag and drop, then rescan, etc.
At any rate, it's nice enough and works fairly slick. It be nice to have a semi-automated option, where I can review the trailer prior to downloading it. Though that may be wishful thinking as the development may of become vapour
Either way, many thanks as I'll be using this for now!
