i run the mythfrontend on a shield and also use the hdhomerun quattro
as well as hdpvr. the files play without stutter and any frontend
features i use all work. i do have to use a cheap usb wireless backlit
keyboard to do edits and other functions as the remote is limited (at
least for me). that was another 10 dollars. i can't answer about
question on dvb streams but i think if u.s. mpeg2 hd plays those would
also play. i have mpeg2 files that go over 6gigs/hour. only issue i had
was on hdpvr content or other iptv content in h265 that i had to change
codec. but they play. 

i don't know firestick 4k, but i had a cheap box with the s905x arm,
same as mibox, and it was pretty bad on mythfrontend. shield a world of
difference on mythfrontend and everything else. i did put libreelec on
the cheap box and kodi worked really well fwiw. hope that answers some
of your questions.
