This is also becoming and issue on the ISP side. These IPTV services are causing support calls for slow speeds and tv freezes when in reality it is just the pirate streams having issues.
A service I am aware of has HTTP streams. Video on Demand streams are rate limited by the server to a fixed rate, which is sometimes significantly under the peak bitrate of the file; and the recommended player device doesn't have a large enough buffer for that.
That's 100% a service provider issue.
Live streams have some issues too, but I haven't debugged those. On the other hand, ESPN+ live streams aren't exactly five nines of quality either.
