Zgemma H2s boxes work fine with IPTV and any bad freezing is normally down to your supplier.All iptv has some freezing now and again but I don't get that much. As
for apps, I have tried them but prefer script method and sly style menu but that's just my preference.Also you can use IPTV player on H2s for movies and tv series.Never buy IPTV from anywhere like ebay,
post a request this forum in the IPTV section and you will find a good supplier.Always take a test first, try it out , only buy from long term members ,not new members and you will be fine .
