Live channels and the movies library do not share the same delivery path. Live TV streams from an encoder that is actively pushing a signal in real time, while VOD serves pre-recorded files sitting in storage. A fault, maintenance window, or overloaded encoder on the live side has no reason to touch a file sitting in a VOD library, which is exactly why one can break while the other keeps working. If VOD plays cleanly, you have already ruled out your app installation, your login, and your internet connection as the cause, because all three would affect VOD too. That leaves the live feed itself as the fault, which is a provider-side problem you cannot fix from a settings menu.

Scope the failure before assuming the worst. Try a channel from a different category than the one that failed. If that other group plays fine, the fault is scoped to one source feed, not your account or your connection, and reporting the specific group gets it fixed faster than reporting the whole app. If every live channel across every group fails at once while VOD still works, that points to a session or line-level issue rather than one broken feed, and re-entering your Xtream login is worth trying before anything else.

1. 1One channel down: source-side, try switch-away-and-back
2. 2One group down: report that group specifically
3. 3All live down, VOD fine: check your login session

Yes, and it is the fastest test available. Leave the frozen channel, go to a different one, then come straight back. If the picture recovers, the session itself had stalled and your bandwidth was never the problem, since a bandwidth issue would not clear just from reloading the same feed. If it freezes again immediately after switching back, that rules out a one-off glitch and points to a genuine capacity or encoder issue on that channel. This single test tells you more in ten seconds than restarting your router or app ever will.

Live viewing concentrates hard around evening hours and marquee sport, which is when provider-side capacity gets tested the most. If freezing is scoped to peak hours across many channels at once, no local setting fixes oversold capacity on the delivery side, and pretending otherwise just wastes your evening chasing router restarts that were never going to help. This is exactly why a provider's uptime number matters more than its channel count: 99.99% uptime works out to about 53 minutes of downtime a year, which is a checkable claim you can hold a service to, unlike a vague promise of reliability that never gets tested at 8pm on a Sunday.
