I have a zgemma h7s running openatv 7.3. Everything is fine apart from all the recent added VOD all I have is sound with a black screen. I have another zgemma which is an h8 and added the m3u which all worked fine. I also have an octagon sf8008 which did exactly the same and wouldn't play newly added. I've tried the latest openpli and Tried numerous hdmi cables, tvs and no joy. Anyone?
