Mine has been pretty stable on the shield since enabling background 
mode. This is what requires force stop. It also allows fast recovery 
after sleep. I havent need force stop for quite a while now as recovery 
is fast and this was the only reason I needed force stop in the past.

I do see an issue where playback pauses after it has been running 
(though not playback continuously) for a long while (multiple days). A 
shutdown of myth and then restart fixes this. I suspect this is due to a 
leak somewhere. On linux mythfrontend in top uses 10.9 G of virtual mem 
but I dont know where this is required.

I did try on my H96pro (S912 based) a few weeks back and was less than 
successful. I suspect ram bus performance is an issue contributing to 
this. I can make this apk available if required but should be equivalent 
to peter's (apr 25).

I am also using wired network.

I havent tried the render branch yet.
