Why do some streams:-
Freeze for a second maybe 3
Buffer
Go into a "loop" where video and sound abruptly stops and the last say 10 seconds of live TV is replayed then things carry on as normal.
These happen quite a lot, not just on your service though.
Why?
And its not my ISP or Router or Devices, because everyone using IPTV that I know (~50 people) have the SAME problems and they use different ISPs, different devices and some are not even in the same country.
I accept its part of IPTV but whats going on?
Might be overheating of your TVbox, try to put it on the side so air circulate better around it. You can also try to put a fan next to it to see if that helps.
