hmmm i'm not so much of a user interface designer..

but i'd say either as two more of the square buttons ("|<" and ">|") or as a submenu, like the audio/subtitle tracks.

another idea that just came to my mind:

You could replace the rewind and fast-forward buttons with last/next chapter buttons if chapters are available, because rewind/fast-forward would still be possible in the progress bar.

The buttons could even be permanently replaced, if no chapters are available they could simply jump something like 5 mins +/-.

I wish there was an edit feature...

two more things:
1) I do still like the submenu idea, too.
2) another great thing would be to display the chapter name after changing to a chapter. Kind of like a subtitle, probably at the top of the screen, with a nice fade-out-effect

1) like the idea of a submenu showing chapters list (bullet list or number list)
2) dislike. If there is a subtitle though ? can't read...

< and > is for rewind forward if I remember ?
<< or |< could be next in playlist for music but next chapter for video if you dont planning video playlist.

@2: you're right, that could be a problem. but I think at the start of a chapter is hardly ever a subtitle (a scene normally starts with an establishing shot, not directly with a dialogue). Furthermore I suggested to put the scene title at the top of the screen. I think collisions can be avoided that way, but I would make that title display an optional feature anyway.

We already have a chapter layout screen. There is a button that displays the "thumbnails" for every 2 minutes or so.

The only change needed is to display correct chapter thumbnails (if available) instead of the standard "every X minutes"...

So, we already have "standard/general" (thumbnail every 2 minutes etc...) chapter support. We just need support to read the chapter timeline, and update the thumbnail layout to reflect this change. Possibly display the chapter name in the middle of the screen when you highlight a chapter thumbnail. This is easy to read, and the chapter can disappear or quickly fade after you select/enter the desired chapter.

Another option is to display the title directly above the thumbnails, but the layout space is very small, so I'm not sure we can fit much text here...

You really don't have to worry about the chapter title covering up anything important (like subtitles) if you make it disappear instantly after selecting/enabling the chapter.

It would only be a problem if you used a long fade away effect.

When I get a chance to take a screenshot of Showtime with the thumbnail layout open I'll make an example picture to upload here so everyone can give feedback.
