Hello!
I have been using the Smart IPTV app on my Samsung Smart TV for a little over a year now switching from priime iptv (now called shark I think) to helix (thanks to many reviews here).
The problem I'm facing now is an abnormal amount of freezes, asynchronous audio and general downtime.
I have tried on five different TVs in five different homes, the only thing they all have in common is using the app Smart IPTV. Though convenient I fear this might be the cause for the problems I have had in the past (e.g. freezes in 30 second periods, whereas VLC froze less on my PC or did not freeze at all).
tl;dr: My question is: Will using a MAG box make any difference? What do I need to prepare myself for when using a box?
Could be both the app and or helix. With say STB emu app for Android you can change the default player the app uses which can help. With that smart TV app you can't do this, when the app loads click ok till you reach the system page, in portals click load portal delay set high see does that help. try change from WiFi to Ethernet cable if not already. I also have helix on Samsung TV same as you, use as my backup . Main provider on my shield TV through emu app which rarely has issues. Best bet try get a trial with a second provider (you can have multiple providers on the Samsung app) and compare.
