Major League Baseball Advanced Media is introducing its new Web-based media player (version 5.0), for those who currently subscribe or those who sign up now for MLB.TV Premium ($114.99 a year or $24.99 a month) or regular MLB.TV ($94.99/$19.99). You'll notice the difference right away as the HD media player has an in-page layout, so it all happens in your browser with no need for an additional download.
