I have successfully transferred mp4 files from PC to Foxsat HDR using TsMuxer and AV2HDR. The audio streams needed to be transcoded from AAC to AC3 format with FFmpeg. My problem is, I cannot get an .srt subtitle stream to be copied over to the Humax. TsMuxer will mux the .srt into the .ts file, which plays correctly with VLC and displays the subtitles without a problem. AV2HDR transfers the .ts file to the HDR, but no ST data is present on playback. This is confirmed by playing the HDR's .ts file in VLC over the LAN. What am I missing ?
