Just to add my experience with the 9.0 update, I have v30 backend and a v30
frontend and after the update I have audio sync issues with both recorded
and live tv (paused a few seconds).  It's like the video is occasionally
choppy, and the audio fluctuates from almost synced to maybe a half second
off.  I haven't tried playing with any video settings yet, I have a v31 apk
to try as well.

On first launch I get a "this app was built for a different version of
android" message, if I build from source will it fix that?
