If you're a sports fan, then you may well get a lot from CyberLink MagicSports, which facilitates simultaneous sports viewing as well as the editing of sports packages.
CyberLink MagicSports is designed to put you in the directors chair, giving you greater control over recorded TV sports programs by allowing you to create your own action replays of key moments. However, it only works with CyberLink PowerCinema 4 or Windows Media Center so if you're not streaming your sports events through either of these mediums, then it's not much use to you. It also won't work with any content that's protected by DRM.
In reality, CyberLink MagicSports is basically a Tivo player for your PC. You can store certain parts of games on your hard drive and create your own highlights with a simple editor. It features a virtual remote control to control your viewing. However, it's unclear how many sports fans would really want to edit together their own highlights package - most people just want to sit back with a cold beer and enjoy the game.
If you're a die-hard sports fan and want to relive a special sporting moment in the way of your choosing, then CyberLink MagicSports is a powerful all round package.
