Won't play when streaming to PS4

[contentfree]

Plex Server is 0.9.2 on Mac OS X and is being accessed by the PS4's browser.

Trying to stream a movie from it automatically pauses after the four seconds, while the trying to stream the same movie on my laptop (connecting to the same Plex server) correctly plays.

From the logs after clicking the final play button:

Additionally, this is the info section re: the browser from the same logs:
