4k29.97 playback issue

Hey all,

On a Vero4K+ when trying to playback multiple different 4K29.97 videos I get similar output to the below. Kodi keeps playing but the TV says no signal.

The vero is plugged into a Denon 4500H amp that’s plugged into a Samsung Q9FN - the amp’s videon “in” information which usually shows the details of what the vero is pushing is oddly blank - I’m pretty confident that everything in the pipeline supports 4K29.97 playback!

(4K24 works totally fine)

Any ideas of what I could poke to get this working would be greatly appreciated!
