Recently Youtube have updated their service and you can now choose 4K streaming (if the video was uploaded in 4K). (it used to say original but it would play anything over 1080 in the past)
I have a 4K TV connected to my Computer ...

Yes the videos on youtube look great ...

I have a 100/50 UFB connection and it would use around 50Mbps for about 10 seconds and then wait 10 seconds and not download anything and repeats.. but it can peak to around 100Mbps at times.. With a 30/10 connection it uses the 30Mbps for about 80% of the time (depending on what is on the screen)

As far as I know its not using VP9 (google's new codec) and I tried Chrome with flash and html youtube. unless there is a secret option to turn on on Chrome

As far as I know its not using VP9 (as it used the same bandwidth on IE/Flash/Chrome/HTML5) (Unless I'm wrong). Maybe there is a secret option in chrome to enable VP9 on youtube?

Also I tested with a slower bandwidth than a 30Mbps Connection and it just I think 30Mbps is about as small as you'll go with 4K on youtube (at the moment).

Also Wifi might be a limit for a few people these days with older wifi (or even new) systems.

The buffer... play you refer to is youtube's dash playback, by default it's enabled for all vids. It will only load a section of the video at a time.

i on the other hand had been eyeing this panasonic 65" plasma. fortunately the lingering 4K standard has saved me 3-5K for the last 2 years :D

(i have a 50" plasma)
