PlexMediaServer Movie in 2 parts

The ATV Infuse 7 Pro skips second part?

Following Plex naming convention.
Eg : Movie.Title.1080p-x264.pt1.mkv & Movie.Title.1080p-x264.pt2.mkv
Plays fine on ATV Plex Media Player.

Am I missing something?

Do these appear as separate files in Infuse? If so, if you enable Continuous Playback in Infuse > Settings > Playback, Infuse should play the next video automatically.

There is also a suggestion thread for adding full support for multipart videos, which you can follow/support here.
