It's the same for me. Force stops are very rare nowadays for me.

I suspect MythTV is too heavyweight for systems like the FireTVs and
H96Pros. Those systems are probably better off having background
processing turned off. Is there anyway an installed app can toggle
that setting itself? If not, we might have to build separate apks
with and without background processing enabled.

I'm all wired too.

I've dabbled with it a little on my Shields but not since the
background processing issues got resolved. I've been waiting for the
elusive, free time and for Mark K to merge those changes into the
render branch. Note that he might have already merged them. I've
just been too busy to check.
