I have an 8TB HDD with MKV shows and movies on it network shared plugged into my router. I'm able to use the Xbox One VLC app to watch MKVs on that drive. However, I also have some subtitle files on that drive and I want to use them in a show. When I select "add subtitle" in the VLC app, the file dialog that shows only looks at the Xbox's HDD, not the 8TB where the videos and subtitle files are. How can I navigate to the external drive for subtitles? Thanks.
Subtitles are .ass file extension.
