I find it easier just to play OGM/MKV files as is. Really, to thoose of you who don't want to spen too much time converting everything u dl as this, grab Video LAN Client - videolan.org - as its a one stop place to play anything. The only real reason to convert OGM and MKV to AVI is for making a VCD or DVD using Nero or other software till they decide to support the more powerful file types. I actually prefer to get things in theese formats so i can switch between sub and dub depending on weather or not i can look at the screen or not.
