This is not an answer to the question. The OP converts **from** MKV **to** M2TS. There are no playlists in this case. Your answer describes the opposite process.

<p><strong>Question</strong> - Why aren't chapters being added to my m2ts using tsmuxer?</p>
<p><strong>Background</strong> I have a mkv file with 61 chapters. I confirmed the presence of those chapters by using mkvtoolnix. I want to convert the mkv to a bluray ISO. But whenever I use tsmuxer, the produced m2ts file lacks any chapters. I confirmed this by opening the file in VLC player; no chapters are listed.</p>
<p>Please note that I <em>am</em> adding a custom chapters list in tsmuxer.</p>

<p>On the input screen, I can see the video codec is indeed H.264 and the audio is AC3. I've pasted the input view from tsmuxer below.</p>

**Question** - Why aren't chapters being added to my m2ts using tsmuxer?

**Background** I have a mkv file with 61 chapters. I confirmed the presence of those chapters by using mkvtoolnix. I want to convert the mkv to a bluray ISO. But whenever I use tsmuxer, the produced m2ts file lacks any chapters. I confirmed this by opening the file in VLC player; no chapters are listed.

Please note that I *am* adding a custom chapters list in tsmuxer.

M2TS as a format / container is not able to store chapter information itself. On Blu-Ray disks, the chapter data is stored in the playlist files. Therefore you won't see chapters when you just load an M2TS file in a player.

I am actually a total newbie to this, so I have no clue whether tsMuxeR creates appropriate playlist files when producing the ISO file. If so, you should see the chapters when you load the playlist file into the player, not the M2TS file.
