we upgraded from a 16Mbps ADSL connection to a Fiber install thats getting 122Mbps and 6 ms ping..... BUT

now netflix is buffering and jittery on our TV which is fed via HDMI from an HTPC, only thing out of the norm is we run a getflix DNS as opposed to the SS one from the PC (getflix DNS NOT loaded into the router)...

i cant seem to find any video quality settings on netflix... im assuming it auto adjusts for connection speed... it was buttery smooth on adsl but now seems "digital"..

anything i should be checking?

How is your PC connected to the Internet (router)? Wifi - could easily be that. Cable....then probably something else.

Im thinking its a case of your faster speed is giving you HD or even 4K (depending on your HTPC and TV) and you've hit a limit somewhere. And as above - my first thought is wifi

And try without Getflix too - then you know if its their proxies or your set up.

If you go to Fast what do you see?

Do you have an option to play something in SD to see if it works?

Also if you go to Netflix you can search for a series of videos called Test Patterns. How do they play?

Check you don't have torrents or something else maxing out your upload (or download) bandwidth.

I've found that maxing upload bandwidth can affect downloading performance. Something to do with acknowledgement packages I guess.

Yes, netflix auto adjusts quality.

And, are you using an apple tv? I've found my 4th gen apple tv is often jittery. No idea why, i was wondering if it is some mismatch between tv and the apple tv .

How does it work on another device, e.g. laptop or tablet?

Set Apple TV to 50Hz and match frame rate on.

Netflix is fine at 60Hz but I find all NZ based services jitter at 60Hz, Lightbox, Neon and Freeview.

4th gen ATV changes frame rate to match the source material - only the previous versions where it had a fixed frame rate.

I get shuddering on my Apple tv gen 4... eg, especially noticeable on a panning scene it will freeze for a moment, then catch up.

Settings, Video and Audio

Top ones resolution set to 1080p 50 Hz (4k resolution 50 Hz if 4k Apple TV)

Third one down is match content frame rate, set to on.

If runningman is correct why is the third setting match content there if it does it automatically. Plus from memory it's set to off by default.

Also I notice bad panning etc if set to 60 Hz on resolution, even though frame match on, but can do own tests if wish.

I've done what I put above and it's playing video perfectly from all sources - I haven't updated to TVos 12 so don't know if different under that one.

With OP's case maybe computer unable to handle higher resolution at enough speed. Also try it without the DNS proxy if running that on computer.
