I wish there was some way to get vlc to use external sprite files.

While I'm thinking about it, external chapter files would be great too. Then you could make your own bookmarks without modifying the video file.

You can make a playlist with start-time and stop-time.

That would be a great way to create smyths (streamlined mythbusters).

Thanks, that is something to think about.

Doesn't seem to support multiple chapters on a single file (without janky stopping and starting, that is).
