The MircoSD move from the old X6 Pro to X9S. X9S FW have been updated to latest version (2.1.36). The same MKV file can be played with chapter on ZDMC of X6 Pro. However, X9S can not detect the chapter. Video and audio can be played without any issue. Because the MKV files are music concerts, the chapter is important. The MKV files are made from BD and written by MKVtoolnix. All are created by me with same tool. Just some files can not read chapter. I believe it is a bug (All can read chapter on X6 Pro, but some cannot on X9S), and How to find a error log or error dump for debug? Media info of chapter can not be read ================================================================= General Unique ID : 224692740880597163813438693681464097260 (0xA90A3F6F7B8715BE84F620CA865439EC) Complete name : D:\Musics\[演唱會]\Jimmy Lo 2016 Concert.mkv Format : Matroska Format version : Version 4 / Version 2 File size : 14.6 GiB Duration : 2 h 18 min Overall bit rate mode : Variable Overall bit rate : 15.1 Mb/s Movie name : 歌詞大師盧國沾作品演唱會 Encoded date : UTC 2017-03-18 05:41:57 Writing application : mkvmerge v9.9.0 ('Pick Up') 64bit Writing library : libebml v1.3.4 + libmatroska v1.4.5 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High@L4.1 Format settings : CABAC / 4 Ref Frames Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Codec ID : V_MPEG4/ISO/AVC Duration : 2 h 18 min Bit rate mode : Variable Maximum bit rate : 50.0 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 29.970 (30000/1001) FPS Standard : Component Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Title : Jimmy Lo 2016 Concert Language : Chinese Default : Yes Forced : No Color range : Limited Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709 Audio #1 ID : 2 Format : DTS Format/Info : Digital Theater Systems Format profile : MA / 96/24 / Core Codec ID : A_DTS Duration : 2 h 18 min Bit rate mode : Variable / Constant / Constant Bit rate : Unknown / 1 509 kb/s / 1 509 kb/s Channel(s) : 6 channels Channel positions : Front: L C R, Side: L R, LFE Sampling rate : 96.0 kHz / 96.0 kHz / 48.0 kHz Frame rate : 93.750 FPS (512 SPF) Bit depth : 24 bits Compression mode : Lossless / Lossy / Lossy Title : Live Language : Chinese Default : Yes Forced : No Audio #2 ID : 3 Format : DTS Format/Info : Digital Theater Systems Format profile : MA / 96/24 / Core Codec ID : A_DTS Duration : 2 h 18 min Bit rate mode : Variable / Constant / Constant Bit rate : Unknown / 1 509 kb/s / 1 509 kb/s Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 96.0 kHz / 96.0 kHz / 48.0 kHz Frame rate : 93.750 FPS (512 SPF) Bit depth : 24 bits Compression mode : Lossless / Lossy / Lossy Title : Karaoke Language : Chinese Default : No Forced : No Text ID : 4 Format : PGS Muxing mode : zlib Codec ID : S_HDMV/PGS Codec ID/Info : Picture based subtitle format used on BDs/HD-DVDs Title : Lyric Language : Chinese Default : Yes Forced : No Menu 00:00:00.000 : zhrologue 00:03:54.467 : zh:大內群英 - 葉振棠 00:05:59.525 : zh:太極張三豐 - 葉振棠 00:07:13.866 : zh:大俠霍元甲 - 葉振棠 00:10:52.985 : zh:浴血太平山 - 葉振棠 00:13:25.271 : zh:浮生六劫 - 葉振棠 00:17:08.460 : zh:換到千般恨 - 柳影虹 00:23:09.654 : zh:少女慈禧 - 柳影虹 00:26:12.237 : zh:怒劍鳴 - 李龍基 00:29:38.977 : zh:浣花洗劍錄 - 李龍基 00:34:41.546 : zh:醉眼看世界 - 李龍基 00:38:41.852 : zh:變色龍 - 雷安娜 00:44:27.831 : zh:愛是這樣甜 - 雷安娜 00:47:10.060 : zh:簾捲西風 - 麥潔文 00:54:20.924 : zh:夢想號黃包車 - 麥潔文/胡琳 00:59:31.401 : zh:今生無悔 - 胡琳 01:03:27.270 : zh:鼓浪嶼 - 區瑞強 01:10:11.307 : zh:漁火閃閃 - 區瑞強 01:13:14.990 : zh:雪中情 - C All Star 01:17:19.701 : zh:俠盜風流 - 陳秀雯 01:19:16.985 : zh:湖海爭霸錄 - 陳秀雯 01:25:16.511 : zh:戲劇人生 - 陳秀雯 01:28:49.824 : zh:明日話今天 - 陳秀雯 01:34:04.438 : zh:殘夢 - 陳秀雯/羅嘉良 01:37:50.464 : zh:天龍訣 - 羅嘉良 01:42:39.419 : zh:秦始皇 - 羅嘉良 01:46:14.668 : zh:人在旅途灑淚時 - 雷安娜/羅嘉良 01:49:55.422 : zh:相識也是緣份 - 張德蘭 01:53:40.814 : zh:情若無花不結果 - 張德蘭 02:02:11.857 : zh:盡與今宵 - 薰妮 02:10:29.988 : zh:每當變幻時 - 薰妮 02:14:15.714 : zh:前程錦繡 - 群星
