I'm curious about this too. I thought the whole purpose of this was when you are "donating" for these services, the network would be better. I don't mean this in a snotty way. I mean this is an exhaustive "I've tried all kinds of live streaming and wish I could just buy my way out of it."
Could it be because of the reseller? For instance, would this be faster if I was using iksrocket instead of iptv66 or something? I feel like they are all just reselling access to stalker, so probably not.
Anyway, I hope someone knows. This is not because of my cache settings or connection. This is a source problem.
