How do you play MKV videos on Mac? My mac is ver. 10.6.8. I've tried VLC, Quicktime(with Perian), DivX and some other. None worked. VLC is probably the most successful one, it can play the video but there's no audio. The vlc error window shows that "VLC does not support the video or audio format 'cook'. Unfortunately there is no way for you to fix this." Help?
