What do you mean avi is dead? Avi isn't really a format. It's just a wrapper for nearly any kind of video and audio. Video can be compressed in any format (divx, xvid, mpeg4) and the audio can be anything as well (wav, mp3, mp2, ac3, ect.)
When I said it's dead I didnt mean people not using it anymore, but dead as in no longer developed anymore. Development stopped more than 2 years ago. In today standards, avi is old and outdated. For instance, it doesnt support b frames nor mp3 audio, but those were added later by means of hacks. mkv. on the other hand is still being updated. The drawbacks of using mkv are processing power and the need for additional software such as matsorka pack ( unless you are using MPC) .
And lets clear something here. DivX, Xvid, H.264, AVC...etc are codecs. Avi, mkv, ogm..etc are called containers.
Dont get me wrong btw. I am not totaly against avi. or something ( Heck I've always used it so far on my encodes). I am just totally annoyed to see that some of the upcoming codecs might not support avi. Thankfully H.264 (the next Xvid, look forward for that) works on avi. But when you try to encode a 23.976 FPS progressive anime ep with a 29.97 FPS op/ed in avi, you'll see how frustrated you'll be....constant FPS ( meaning that you'll have to decimate the whole ep to a constant FPS, either making the op/ed smooth and the ep jerky or letting the ep go smooth while lagging down the op/ed).
Anyways I am babbling here

If you really dont care then just stick to avi. But if you want to ( and can ) go full quality then you're better off with .mkv
Sorry for dragging this offtopic, heh ^^;
