Hi guys i dont mean to hijack this post but i have been following it as i have a zgemma h7c box myself. on tuner A It has a satellite tuner. On tuner B it has a cable tuner. On tuner C i am lead to belive this is also a cable tuner. the problem i have is i can record satellite channels ok. i can also record 1 cable channel if i try to record 2 cable channels at the same time for some reason it wont. After following this post i am now thinking that tuner A is for satellite. and tuner B is for cable. and tuner C is for terestrial tv . when i purchased the box i was thinking this box was for 1x satellite tuner and 2x cable tuners . this box has really done my head in any advice would be good.
