Missing Files
So I have been using Serviio for 6-8 months now and I REALLY like it. I have seen that many people have had various issues seeing all files using Serviio, and most of them are for different reasons, But since the beginning I have been dealing with an issue I cannot figure out. Most of my videos come up with no issues, but sometimes I have videos that only show up when I browse to the folder (so they don't show up in 'Movies' 'Titles' 'Directors' but I can see them in 'Folders' when I browse down). Most of those were my young daughter's movies (kids movies) so I didn't worry about it much, but I just assumed Serviio didn't recognize the metadata or something and thus wouldn't see the files to put them in all folders, but would at least show them in the folder view. But now, I have all 3 Lord of the Ring movies that are in .mp4 (sorry I don't know more details off the top of my head), and I cannot get Serviio to see the files at all... Any thoughts on how to correct this?
I have tried to reinstall the application (multiple PCs just incase) and tried to delete all drives and add them back into Serviio and no luck. All of my media is locally attached to my PC.
Thank you for any help you may have...

--- (additional) Okay, so I did some more searching about my Lord of the Rings, and I think that is because they have a DRM on them... any thoughts about some of my other movies? Why would they only show up in the 'folders' folder and not 'Movies' 'Titles' and so on?
