USB drive doesn't show in nitoTV

I’ve mounted an external USB drive (LAcie Grand 1tb) to my Apple TV. I’ve run smart installer. I can see the USB drive and the movie files on there through FILES - PLACES. But I can’t play them here (the movie files are shown as VideoTS and Audio TS).
When I go through Sapphire and / or Nito TV the movies on the USB drive doesn’t show.
How do I get them to show, and how do I get them to play?

Furthermore. When I connect through FTP, I can’t see my external drive?

Thanks in advance for your help on this.

cheers

Your may try connecting the drive AFTER the AppleTV powers up as some drives work better this way.

Thanks. That worked…
