I am in the UK
Frame rate switching can be done on the pi without a reboot, I don't
know the technical details.
Kodi can and does do this ( by default it is off but can be enabled to
run at stop/start). I have just tried this with my Samsung TV and it
auto switched from 50Hz to 24Hz, when I played 24p video content and
back to 50Hz
Note Kodi 17.4 Git:20170822-d640e9a747-di is now in Raspbian repo for
Debian Stretch, as is the kodi- pvr.mythtv plugin (which works with my
mythtv 30-pre backend).
For Live TV change Tuning timeout (pvr.mythtv Advanced tab) from 5
seconds to 10 seconds when using DVB-T/T2 tuners in mythbackend,
otherwise you might get Channel Unavailable message.
