I have just purchased and installed the ATV Flash XBMC edition.
Everything is working well except for one small issue.
The install I had of XBMC before allowed me to use the forward and back buttons for chapter jump. This feature is no longer available. Oddly if I press the chapter jump right when the movie starts, it seems to jump the time distance of the first chapter. But it does not change the chapter indicator to reflect the chapter I am on, nor does it allow me to jump forward or back after that one time.
Is there a setting that can be adjusted to allow for chapter jumping?
