Sorry this is for the desktop... not the n810.


I have the exact answer to this..

Script for HD -

javascript:if(document.location.href.match(/http:\/\/[a-zA-Z\.]*youtube\.com\/watch/)){document.location.href='http://www.youtube.com/get_video?fmt=22&video_id='+swfArgs['video_id']+'&t='+swfArgs['t']}

Script for HQ

javascript:if(document.location.href.match(/http:\/\/[a-zA-Z\.]*youtube\.com\/watch/)){document.location.href='http://www.youtube.com/get_video?fmt=18&video_id='+swfArgs['video_id']+'&t='+swfArgs['t']}

Save them as separate bookmarks and click on it on the respective youtube page....
