Well, i cant speak for anyone that seems to be having a problem but i love this service.
EVERY channel that i watch loads in under 5 seconds, most are now in glorious HD and i dont get any buffering, stutters or anything.
So i'll speak of my experience with this service.... i love it and would recommend it to all who wants an easy to setup, fast loading HD IPTV service.
tifossi's service is my goto iptv provider.
