I used to play flv and mkv video files in my laptop before. But a few months back, I had to install the Combined community codec pack for a video converter program. So now, (I don't really know exactly what happened) I can no longer play flv and mkv file formats. Media player classic shows a prompt about not being able to render the file and that I may not have the necessary codec to play the video. Uninstalling the CCCP didn't really solve the problem. I have the K-lite codec pack (ver. 7.2.0) installed before I got the CCCP and I have not touched it whatsoever, for fear that I might cause more trouble. SO, my question is, how can I restore my codec setting to be able to play flv and mkv video files again?
