Ok i found a solution, its very easy, but not obvious to find, if u want to play ur HLS IPTV list from a bouquet on your enigma2 box, all you have to do is install ServiceApp, then in openvix settings > system, open ServiceApp, and change Enigma2 playback system to - serviceapp, and thats it, from now on HLS streams work like a charm, also recordings seem to work better with that new player too.
The only other thing i would change there, is the bitrate to the ammount that suits you, if u want to save some bandwidth ofc, like if ure on mobile or something, but it only works, if the provider allows you to chose different resolution/quality stream.
