jQuery News Ticker - not quite smooth enough

Hey, I have a nice news ticker that stops on mouseover etc... but the animation is slightly jerky - any ideas?

var ticker_holder = $('#ticker').get(0);
            var ticker_text = $('#ticker').get(0);
            var ticker_pos = ticker_text.parentNode.offsetWidth;

            var ticker_data = "<strong>Featured: </strong>"
            +"HardCoded, DamnCool, AliveKicking, NinjaGaiden, WikiWord, FeaturedWords...";
    开发者_如何学编程        $(ticker_text).html('<marquee scrollamount="1" scrolldelay="20">' + ticker_data + '</marquee>');

            $('#ticker').hover(
                function() { $('marquee', this).get(0).stop();  },
                function() { $('marquee', this).get(0).start(); }
            );
