Also an old PC with a good Nvidia graphics card with do the job. For me form factor is also a big issue. That's why I spent a lot of time debugging performance on the 3rd gen Core i3 NUC. But that performance is going down not up.

I'm following this thread (and a related thread on mythtv-dev) with interest.

I have a 29.1-fixes combined backend and frontend running on an ASUS Q87T mobo with Intel Core i5-4460S CPU and integrated Intel graphics. This all works pretty well and mythfrontend's playback of my UK DVB-S2 HD (AVC/H.264 1080) content using VAAPI is perfectly watchable, although fast-panning scenes and fast-moving credits show that it is only just able to cope. 

As a number of other users have commented, mythfrontend's skipping performance blows anything KODI-related out of the water, yet KODI's visual appearance exceeds that of mythfrontend

I'm looking for alternative frontends and so far I have tested an RPi3 running Libreelec with KODI's mythtv-pvr plugin, and while its visual appearance beats that of mythfrontend, the skipping performance is a bit of a disaster.

I've also installed Peter Bennett's Android frontend APK on a Xiaomi Mi-box (S905X Quad-Cortex-A53 @2.0GHz, Mali 450 @750MHz, 2GB DDR3, 8GB eMMC, 5GHz WiFi) but surprisingly this won't play any of my HD recordings without severe stuttering. Even my SD recordings seem to struggle on this box, which surprises me given the graphics hardware performance claims, which as I'm typing this is making me wonder if I have a WiFi performance problem.

I'm considering trying a FireStick4k (I can't justify GBP150+ for a Shield) but am sceptical that this hardware will perform any better than my MiBox. Can anyone verify decent quality playback of HD UK DVB-S content on any Android hardware?
