For now, writing MJPEG-2000 animations is a waste of time because
there's very little software to play the file or convert it to
something else. You're better off writing from IDL straight to the
format you want. There's some discussion on this right now on a thread
entitled "animated png: a new format for scientific animations".

In addition to being poorly supported, MJPEG-2000 suffers another
limitation that makes it not very good for scientific animations: it
fails to make any use of inter-frame compression methods. This means
the files are much larger than they need to be.
