Be aware of that S905X4-J in rev d (e.g. HD Dune Pro Vision 4k) has issues with playback of H264 1080i (white artifacts) in combination with kernel 4.9 (CE-NG) which in turn is the only version still supporting DV FEL as in later kernel version 5.x Amlogic dropped support. So you will either get 1080i playback working properly with CE-NE or DV FEL with CE-NG but not both. Thanks to @YadaYada for this information.
