i think this is possible but really not sure how too do it. essentially there's plug-in's, scripts and third party websites like:
http://1024k.de/bookmarklets/video-bookmarklets.html is one site with scripts for example.
or translater websites but i can't seem to find those anymore.
so does anyone do this? does it work well? please post tips and how too. i'd also really like to know what the difference in the quality is like.
from my googling it seems they're all geared to windows users.
oh and of course any good finds for video clips then post in the comments too!!
