I am getting good with results with a Pi 4 using the devel/2019-render branch which has just been merged into master. Performance on a Pi3 was poor and its best to stick with fixes/30 for now.
On the Pi4 playback was better than fixes/30 for me, there is less judder when panning 1080i content but unfortunately still some.
I am selecting the v4l2 profile for playback.
AFD: Using v4l2-dec for video decoding
VideoOutput: Allowed renderers (filt: v4l2-dec): opengl,opengl-yv12
A couple of points to note:-
Has any one got a video timing method other than USleep with busy wait to work?
VSYNC: DRMVideoSync: VBlank ioctl did not work, unimplemented in this driver?

On my system the display refresh detected by the frontend is the monitor default not the actual currently selected rate. Monitors tend to default to 60Hz but in the UK most TV is 50Hz.
Has anybody using 50Hz got it to work properly?
