newclock3 is rebased off a newer point in Gotham. You either need to update xbmc in OpenELEC (with makepkg) to the same point,
or (what I did) rebase newclock3 onto a branch created from 7f45288, and then create the patches form there.

Thanks, I'll look into the makepkg option as I'm just downloading your patches over http rather than forking/cloning your repository.

I believe the whole directory is iterated, and then each file is compared with a valid subtitle filename, so the time taken is proportional to the number of files in the directory.
With a thousand moveies, each with a collection of artwork, nfo files and subs, I could imagine this taking a couple of seconds (although I keep things as hieracrhical as possible, so haven't tried this).

Although I don't have thousands of files in each directory, this sounds like it could be optimised...
