M3U channels keep on skipping

Hi guys I need your help.

I am running osmc (latest) on a raspberry pi 3B+ but I am experiencing an issue when playing iptv channels from an m3u feed.
The channels are working but about every 10 seconds it skips to the next channel and so on. I don’t know how to solve this annoying issue
It does it on all m3us I tried

Could you help me please ?
Thanks in advance

How many channels are in your list?

Around 1500
