2.
3.

What is the expected output? What do you see instead?
Dropping frames causing video stuttering, audio is OK. And Judder content

Latest Chromecast.

Please provide any additional information below.
Hey please... It can't be true, that Google is ignorant with this issue. The 
product is sold all over Europe, and the device is fixed to 60hz output?!?! 
Xbox One, have made the same stund/fault, but they have now fixed there 
software, with a 60/50hz menu. Drop the sale in Europe, or make a fix.. Please.!

Just got a chromecast as a xmas gift, installed last night. Now I am enjoying 
juddering films and choppy panning in every film I try to watch. Very 
refreshing. This one goes straight into the bin.

This is clearly a bug, as this issue is fixable by Play/Pausing the video 2-3 
times (you don't have to wait, just play/pause repeatedly). Tested myself and 
it instantly fixes the problem in Netflix and Hulu.

Found this solution here:

Without the Play/Pause trick it appears as if Chromecast is dropping frames 
while buffering in the background for the higher quality streams. Usually after 
3-5 minutes, this effect disappears. While this is OK for Netflix, in Hulu you 
get commercials that interrupt the streaming so this happens again and again.

I don't experience this problem in YouTube.

In conclusion I think something could be done about without implementing 50Hz 
support.
