I have to agree i wish i had never bothered with it i am having trouble with the jitters on Netflix and 4k on youtube is no better. It has got to the stage where i now watch most of my entertainment through the apps and freeview on my 4k tv. I even had my V6 box replaced 2 days ago and its even worse than the one it replaced as i now have intermittent sound aswell as all the other issues.Everything i record is jittery aswell and the picture quality through the V6 while watching normal tv is poor at best. Even the engineer said the V6 box is very temperamental !!! Im now looking to get rid of the V6 and just keep my broadband and phone which i dont have a problem with but i expect that will be another battle!
