codec

Hi, I'm having some problems with my IPTV service. Nothing new here, I know It's a paid service and recently some of the channels, mainly UHD - 4K will not show on my Vu+ solo 4k. I'm running Blackhole 3.0.9.N on Vu+ Solo 4k What's more, the channels appear to be Ok, as when I use a Mag box...
