Just gave this a quick test on my H7. Its working fairly well. 24Hz switching worked properly on 1080p and 2160p media. TV channels switched correctly to/from 576/1080/2160 as required except for Saorview (terrestrial) channels in 1440x1080 - these switched to 2160 output which isn't a major problem for me (It may be an issue if someone is using a non-4k tv set). Nasa UHD (60Hz) outputted at 30Hz (but I think that's a limitation of the box).
