By default, KMPlayer does not come with Codecs for RMVB files. They can't, because it would be illegal.I'm unaware if this problem is only on Windows 7, but it is definitely a problem.Even installing the K-Lite Mega Codec Pack doesn't fully fix the problem. The video can be seen, but there is no audio.The fix involves acquiring the Codecs Real Player uses. This can only be done by installing the horrible software, and taking the codecs. Unfortunately, the current version of The KMPlayer is not compatible with the current Real codecs. Or something like that.The fix involves taking the Real codecs from "MPlayer", a Linux movie player. To save any users the hassle of searching for a solution that wont work, and installing a bunch of unnecessary software, I have archived all the necessary codecs.Just download and extract all codecs to the root directory of your KMPlayer install.By default, the directory is:View attachment 2 Extract all codecs to that folder and you'll be all set! Enjoy watching RMVB files on the awesome KMPlayer.
