I get a "noCodecErr" error when I try to use the QT Writer plugin to
save in "Motion JPEG A" format. I looked on the Web for information on
OS X QuickTime codecs (coder/decoder or compressor/decompressor), but
didn't come up with anything. You could try posting a message to the
QuickTime for Java mailing list at
"http://lists.apple.com/mailman/listinfo/quicktime-java".

I got the same error message on Mac OS 9 when I tried to save in "Motion
JPEG A" format. I don't know of a workaround other than saving in a
format that does work, such as "Sorenson Video".

By the way, the OS X ugly text problem is fixed in ImageJ 1.28d.
