Hi everyone! I'd like to tell you what 3D subtitle support you have? I have an X9s device with the latest firmware. I tried to convert from 2d (SRT) to 3d subtitle (ASS) with 3D-Subtitler. The media player can't merge the two up-down subtitle (Half Over-Under). Only can the simple forced or srt subtitle displayed in the 3d movie (MKV). Thank you in advance for your information!
