I have linked my IPTV to my Emby server and I can watch live tv remotly in browsers like Firefox or Safari without transcoding, bur fail to lounch it in Chrome, no matter if it is HLS or TS.
Can someone explain to me why do all lists play smoothly in Firefox and Safari and won't start in Chrome? Should I convert my list somehow?
Because chrome sucks as a media player browser. It lacks support for some codecs. This has nothing to do with your m3u list and more to do with what chrome supports. For example, it does not support h265 at all.
