Well, I may not have anything to suggest.
I have tried to look for this error here in the forum or on the internet only in relation to Kodi, but I did not find anything relevant.
Thanks for trying. If you can i'd appreciate it very much if you want to test the cvbs connection this weekend on lcd tv.

I notice something odd: you can't change the resolution in Kodi. The options under system settings are grayed out... It that the same with your S905 boxes? Hm might have something to do with the disp_cap file in place. Yes it does. I am unable to find a list with resolutions. Why not put 576i wdescreen in there? hmm.
