Real media formats are one of the most popular media formats which can be only played using Real Player. But if you want to play real media files, but don’t want to download Real Player, here is a codec pack, ‘Real Alternative’.
Once downloaded and installed, it plays the Real media file formats in any of the media players like Jet Audio and even in Classic Media Player
I tried Real Alternative and it works pretty fine, moreover I couldn’t make out any difference in quality too i.e. you get the same quality of video or audio what you would get when you play it with real media player. There is an option to download the Light version too for the same codec. Try it, and save yourself from installing another player. Download Real Alternative
