I have the h2s, had a couple of iptv subs up til 2 year ago when I got an xstream sub, was never very happy with it, always glitching, its well known the h2s was neve rmeant for iptv but I read on here that if I put a usb drive in teh back and download a plugin called flash expander it can help with the gltching and it did. I got a a new sub a month ago on here and flawless service, wont be going back to xstream.
