1) I did not have to adjust my video calibration. Are you doing it in the playback options or the kodi settings? If you make a change using the options during playback I think there is an option tI save settings as default. If it is done through kodi settings, I would expect it to be persistent. Maybe there is an xml file that can be updated manually if the setting is not persistent over restarts.
2) There is a pvr.mythtv add-on you can install with pacman:
