Certain subtitle formats cannot be directly streamed, so your server is probably re-encoding video on the fly to burn in the subtitles. PGS format is actually a series of images and will always require re-encoding video. Picking SRT should work with device direct streaming.

That must be it, then. Thankfully I’ve got Bazarr set up to snag SRTs for imported media, so those should generally be available.
