I have ripped We're the Millers Blu-Ray to MKV, with extras and an Extended Cut. The extras and extended cut are not being detected as an alternate version or extras, they are being identified as individual movies. I have followed the instructions in the wiki, to no avail.
The file structure is as follows:
\SERVER\Movies\We're the Millers (2013).H264-DTS.BluRay-1080p\
We're the Millers (2013).H264-DTS.BluRay-1080p.mkv
We're the Millers (2013) - Extended Cut.H264-DTS.BluRay-1080p.mkv
