You need to have real players codecs installed and Gabest's real media direct show filter. If you want a single file download then I guess Real Alt, however it is technically illegal.
Try download and install K-Lite Codec Pack (full or mega version): http://www.free-codecs.com/download/K_Lite_Codec_Pack.htm Happy video viewing!
Well you can't get around the fact that you need to install real codecs, which means either real player or some kind of pack.
