How to jump to next chapter when playing back videos? I'm trying to play back .mp4 videos that have chapters embedded in them. They play fine on desktop players like VLC, and on my iPod, but I can't select/choose/jump to these chapter markers on Android.  What am I missing?
It's likely because the player app you are using is not aware of the embedded chapters.  I recommend searching Google Play Store for video player apps that support this feature.

A quick Google search points to Simple Cinema and XBMC (not on Google Play).  I have not tried these personally, but this should start you off in the right direction.
