I can confirm some of my friends using Samsung aren’t able to play some files.
It looks like whenever a subtitle is enabled this error occurs. For some reason the subtitle track gets “Direct Stream”.
The playback either doesn’t start at all or just stops playing after a while…this is weird.
All this with Direct-Play content, with SRT subtitles included in MKV.
It shows both Video and Audio as Direct Play, while Subtitles (SRT) are Direct Stream. Why would they need to be Direct-Stream-ed?
It also happens with PGS subtitles (these Samsung apparently have PGS support, so no transcoding is happening).
I hope this gets some attention, it would be nice at least having other people confirming this problem or not.
