Hi I'm using a zgemma h5 2s and its been locking up on iptv channels for a good while but now on vods its behaving for the First 30 mins then locking skipping etc ever 2 minutes after being updated to open atv 6.4 and latest grogbuild . Idont believe it is the supplier and after a Google search there is so much about zgemma boxes doing this so what is a easy reliable box to get iptv on any help would be great
