I'm finally trying to get all my Doctor Who into Plex but the bonus features are driving me crazy.

For example in Season 7 there's a bonus video called "Down to Earth"

Nothing I do can make it show up in Plex. I've tried S00E01 - Down To Earth.mkv

I've tried "Down to Earth -featurette.mkv"

I've tried \DoctorWho (1963)\Featurettes\Down to Earth.mkv

If I name it S00E01.mkv and put in into \DoctorWho (1963)\Specials it shows up but its labeled wrong. There are dozens of bonuses for each Season so I don't wan to have to fix every one.
