For now, the Extras will only work in iTunes 9 (Mac and Win). I’m still working on getting support for the AppleTV 3.0 update released last week.
You’ll be able to watch all five sessions of the October conference, as well as the General Relief Society Meeting held on September 26, 2009. (Soon, I’ll release an update that will include the text of the talks, so you can read along as well.) Browse through the sessions, search for your favorite speakers, and enjoy the music of the choirs. Just download, unzip, double-click, and enjoy!
