Ditto. Very slow. Very choppy. I've tried many different connections (home, work, friends, hotels) and nothing seems to work. I have a 2.8ghz cpu with 2 gigs of ram and a great graphics card and joost looks like total crap.
If you're misquoted, often it's best to just let it go. No matter how hard you try, not only are you going to peeve of the journalist(s), but you're not going to get much sympathy. I think the value of blogs isn't that you can try to repair damage, it's that you can more carefully think about what you're saying and be your own publisher! :)
