Using DVB-T/T2 in the UK I find that the Leanfront on a 4K
Firestick is <br>
excellent when it works, but it still seems to need purely
progressive <br>
content and that often can't be guaranteed. I have GT710s,
which are <br>
less capable than your GT1030, and they lack smoothness in
panning when <br>
using nvdec hardware decoding. But with i5 4-core 3 GHz
software <br>
decoding, playback is as smooth as I get from DLNA or the
leanback on <br>
appropriate content. I haven't seen what newer and cheaper
devices can <br>
do, but I'm sceptical. I think you ought to try software
decoding on <br>
your i7.<br>
<br>
And I recently noticed that the leanfront seems to work well
with live <br>
DVB-T mpeg2 material, while recordings now have good audio
but the video <br>
pauses briefly about once a second and sync is terrible...<br>

With v31 of the Frontend playback on Intel hardware using
VAAPI is very good. It may be worth unplugging a cheap Nvidia
card and trying the onboard graphics.</div></div></blockquote></div></blockquote><div>In my case the Intel hardware is about 8 years old. Core i7 yes, but Sandy Bridge generation. It is really doing a good job with the GT1030 installed.
