In the most cases the problem is on server side. IPTV provider does not provide enough server performance/bandwidth to keep flowless playback for all of his clients. The issue is mostly noticeable in prime time, when most users are watching TV at the same time.
- Check your network bandwidth
- Use wired Ethernet connection (not Wi-Fi) if available
- Try to select different Buffer size and Decoder
- For unstable streams use “Pause” state to fill buffer in advance
