Sony Bravia KD-49x8309c Judder issue 

Sony's last update has finally fixed the fault seen in the video, I have been running the latest software fault free now for 2 months.

That's one mess of a picture, I've not had this problem.

i have one of these..................try the new firmware update from sony.....google....the model number with firmware update....then follow the steps.......works a treat

check to see if your actually running your output in 4k not 1080p
