I get you, just from my experience, not all channels are 720p, so they're not being entirely honest.
Well the sum total of my DSTV watching is sport when I visit a mate of mine, so I have very limited exposure to their streaming quality.
But, it is becoming an issue, as I am seriously looking to buy an nVidia Shield TV, which does some very good 4K upscaling. But it does not upscale, 1080p @ 60 fps.
If DSTV stream at 1080p @ 60 fps, then I need to get a Shield Pro, as this will upscale 1080p @ 60 fps.
Problem is no one gives and authoritive answer. And as soon as someone gives a answer, Mybb, or some other contradicts it so yeah, like I said, rather confused.
