supo, i kinda saw the video, you need to slow down, cause there is just this hella bad bit rate issue. when you hit your keys. it interferes with your voice,( type gentler)
its a great video overall, but could you slow down and re-post the video again, its seems to be a great video tutorials
Here's a new link, should be better
It doesn't really show you how to clean that much, it shows more typesetting then anything else.
i'm gonna watch it ^^
