PLEASE HELP – iptv problem with HD streams only using kodi 17

Hi

I’ve been using an IPTV provider (smarthub) for many months perfectly fine operating Kodi 16.0 and then 16.1. I recently upgraded to 17.1 and all of a sudden i am unable to play HD live streams only – the FHD and SD streams all play smoothly without issue which is just bizarre. It’s definitely an issue that’s brought about by the upgrade of Kodi version as if i reinstall 16.1 the problem disappears. The streams buffer and the picture becomes pixelated when the problem arises.

I’ve done a bit of research already and have tried adjusting resolution settings and turned off the hd upscaling feature and disabled mediacodec. Nothing has worked and i’m out of ideas!

I’d be massively grateful if anyone can help me out please!!

Thank you
