ReadyDLNA does not find all files (dirs, files missing)

Hi,
I just recently purchased a RN102 (6.0.8 ) and loaded all my media files onto it. It's been on for a few days now so any DLNA indexing services should have had more than enough time to finish.. however, a lot of folders are missing - completely randomly. And some folders contain only half the files - other files appear in wrong places. Why??

I was using a Buffalo WVL before (actually, I still am until I get this sorted out) with Twonky and it worked beautifully. Twonky detected all my files and the directory structure was very good. (it was the same as my directory structure)

With ReadyDLNA as it's now, it's completely unusable. The folder structure isn't even correct! As an example: I have 20 .mpeg files in one directory but this directory is not showing up - instead one of the .mpeg files shows up in the root (in "folder" view on TV). :? How is this even possible? If ReadyDLNA has found the directory and the files in it, why not just show the whole directory? Why would it skip 19 files and "move" the last one to root?

Photos from my last holiday won't even show up. I used 2 cameras, a sony compact and a nikon dlsr. So I have 2 directories called "Sony" and "Nikon". Both contain .jpg's For some reason only Sony shows up :? :? Twonky displays both..

I must have missed something. Where's the re-indexing button? Or how do I install Twonky? (I'm using a SONY 46" EX500 if it matters)
