Most pop-up blocker software will block you from using the the Yahoo! Music Music Video Player. These applications include the Google Toolbar, Panicware, and new versions of Netscape and AOL. There are several ways to work around this software:
http://launchtoday.launch.yahoo.com/player/player.asp
http://launch.yahoo.com/musicvideos/player/playvideo.asp
Neither of these pages will serve ads to you, they only launch the music video player and Yahoo! LAUNCHcast. You will not see more ads by adding these URLs.
If you have problems, contact the company from which you purchased or downloaded the pop-up blocker software and let them know you would like to view content on Yahoo! Music but their software is not allowing you to do so. Their customer service should assist you. If you still have problems, please write to Yahoo! Customer Care, and we will assist you.
