Hi, I just bought the mibox and I am facing this problem, Youtube video keeps buffering, even though I set the quality to 480p, it still keeps buffering. I'm using 8Mb Streamyx. All the other apps such as iFlix and other video streaming app runs smoothly @720p. App from PlayStore also downloading at the correct download speed.

So anyone encounter this problem?

Nope, I didn't enable ipv6. I also tried using TubeMate, is still the same, the video buffers even at very low resolution.

Ok.. Found a workaround. Use TubeMate to find the desired video, click on the full screen icon, then select the video resolution, play it with an external player (MX Player), the video will play smoothly even @1080p.

It's a bit troublesome, but I think I have to use it this way until l find out what's wrong with the Youtube app.
