I truly dislike MKV. I got the second Deathnote movie in that format. It drove me nuts, because I couldn't find a decent program to convert it to .avi so that I could burn it to DVD (my mother wanted to see the movie and a computer screen wasn't going to be an option [I hate sitting in front of a computer for movies too]). I tried and I tried, and I just couldn't get it right. One program worked, but, I couldn't get the subtitles to show up. It was just too much of a hassle. Luckily, someone else had the movie in .avi format, and I downloaded/burned that. Yeah, the MKV version did seem a bit more clearer, but .avi version was easier to manage.
