I'm trying to create chapters for some videos I have. They don't have to be perfectly aligned to each video, just every 10 minutes or so to be used with my WDTV player.

I downloaded MKVmerge, and tried to create chapters with that, and thought that I did, but when I try to add it to the MKV container, I get an error code (I can add a subtitle file just fine though.)

Anyone here know the easiest way to create chapters, that can be muxed with an mkv container?

Thanks.
