Raspberry Pi & youtube

[#1]

Hi all
Anyone else using their pi on youtube? What is the playback like?
I've got gnash installed for a flash player but the playback on YT is very glitchy. Just wondering if anyone else has had issuss with it?
Granted its not the fastest for web browsing but with so much talk of media streamers etc I thought it would be a bit less choppy!

I've only had experience of it running XBMC and playing Youtube stuff through that with the Youtube addon. It worked very well and I could watch up to 720p without too much of a problem.

Very tempted for a R-Pi, might grab one soon.

This Raspberry Pi should have enough power for youtube in HD - http://www.theregister.co.uk/2013/05/20/32_way_raspebrry_pi_cluster/
