I would love to know why DSTV Streaming has a bad quality picture most mornings I watch channel 403 which is eNCA news, It goes blurry and then it come right for a few minutes maybe 30mins or so then back to blurry and also stops playing and then start playing again - None of my other streaming services do this only DSTV and I have a 500Mbps fibre line and the router and apple tv box is connected via cable so there should definitely be no problem, please advise how we can sort this out. THANKS
