Thank you very much!!!
Everything went smoothly so my DM feels brand new and full of potential!!!
I set up my dish straight away and scanned the channels and then I couldn't find the IPTV channels but I looked in Favorites and there they were... not many of them working though... I'm in Greece and not even Greek channels work... I'll keep looking...
I'm trying to install cccam but no luck yet...
Thank you for your help!!!

Are there any 4K (H265) tuners that we can add to our DM8000 to make it receive 4K channels???
