Plex can’t do that. When a single file contains multiple episodes, Plex doesn’t have any way to know where the second episode starts within the file.
Your choices are -
- Splitting the file into two episodes. Both appear and function correctly in Plex. (S01E12, S01E13)
- Using a filename so both episodes appear in Plex. BUT, when you playback either episode, the entire file will play. (S01E12-E13)
- Using only the first episode as the filename. Manually editing the Title and Description in Plex to include the info from both episodes. (S01E12)
VPTs don’t impact Plex’s ability to “seek into” a two-episode file.
