install k-lite mega codecs pack!
Looking at the list it includes;
- RealMedia codecs [version 188.8.131.521]
- RealMedia plugin for Internet Explorer
- RealMedia plugin for Firefox/Mozilla/Netscape/Opera
- RealMedia DirectShow splitter [version 184.108.40.206]
I read that sometimes Real Alt doesn't work with rmvb. Does it work for you? Does this pack make VLC work with rmvb, or does it work through Windows Media Player?
