It could be your end if all the channels that buffer are fhd and the ones that dont are lower resolutionI'm running iptv on a fire tv box hardwired and nvidia, certain channels buffer on both devices but provider says theres no problem at their end . Is it a provider issue if it's certain channels buffering, would all channels buffer if it was my end ? Thanks
