It was kind of hard to make a bi dimensional array in javascript; i struggled a bit when i needed to do so; so tgis is what worked for me eventually:

function createLinksArray() {
var links = new Array(4);
for (i=0; i <= 3; i++) {
links[i]=new Array(2)
}

links[0]['videoURL'] = 'aaa.flv';
links[0]['videoName'] = 'aaa';
links[1]['videoURL'] = 'sss.flv';
links[1]['videoName'] = 'sss';
links[2]['videoURL'] = 'ddd.flv';
links[2]['videoName'] = 'ddd';
links[3]['videoURL'] = 'fff.flv';
links[3]['videoName'] = 'fff';

return links;

}
