I am not a fan of Sky News but I got around to looking at the three IPTV Sky News Extra streams today. I notice that all three have a slight 'tick' every few seconds, not bad enough to make them unwatchable, but noticeable. The stream makes a slight jump or twitch, then carries on until it happens again. All of the other IPTV streams work normally. This only happens with the three Sky News streams. Does anyone else see this and does anyone know what the cause would be? I am not particularly bothered by it, mostly just curious.
