I appreciate the help so far, can you suggest anything else?

Unfortunately not, I'm still having the issue with DNR set to off.

As in try the 4000 on one of the other TVs? I can, but I'm having the same issue with two different sticks on two different brands of TV as it stands (one HDR and one not), so I'm not sure the TVs are the issue. EDIT: In fact thinking of it, before I bought the 4000 I was using one of the Vidsticks on that TV, and had the same issue with juddering on there. That TV is just a 32" 1080p set.

I did check for updates and it's running the latest version, and I do have it setup the same as my 4000, yes.

No, I haven't changed anything on that side of things. I bought them both off of eBay, so they were factory reset just in case before I started using them.

Has anyone else experienced an issue with flickering or juddering pictures from their Vidstick Max on certain 1080 channels? It doesn't happen on all of them, and I'm seeing it on two different devices on two different TVs, and across different services. I don't get the same on my XRS4000 I have in another room, which is what is making me think it's to do with the sticks rather than any service/HDMI port issues. Do you think it's possibly to do with compatibility with the codecs involved, and if it is could it be resolved in a firmware update?
