Does The xbox one app support playback of multipart movie? It plays fine trough part one but stops when part 2 should have started
~~No it currently does not.
The addition of play queues is a step towards having this feature, but I have not seen any word from the developers on the status of this particular feature.~~
See below.
OKay, so just have to wait for update to the xbox app then. Thanks for answere
Sorry for the bad information. Dom C pointed out the error of my ways like the true Ninja Master and stacking does indeed work on the currently release.
Testing it out on a pair of Dragonball Z episodes I was able to get it to work on both Plex Web and the Xbox One app with the following naming:
Dragon Ball.S01E01-pt1,mkv
Dragon Ball.S01E01-pt2.mkv
pt2 was actually the 2nd episode. The time indicator at the bottom of the screen does not change to match both episodes but the app should automatically switch to the second part when you select play. If this is not the case I would verify that Plex Web is indeed picking them up as stacked episodes.
Maybee it was the Movie, i will do some more checking
