The MS-Windows CU-SeeMe MJPEG video codec is not compatible with either
Apple's M-JPEG A or M-JPEG B video codecs.
They also use differing 4 byte identifiers (so Apple's M-JPEG will never
even attempt to decode the Windows M-JPEG video).

Work is currently in progress on a Mac M-JPEG video codec which will be
compatible with Windows version.
We are hoping it will be available in time for our public Mac 3.0 beta
which hopefully will be happening very soon..........

Either way, thanks to QuickTime architecture, it is a plug'n play codec and
can be dropped in your system extension folder at any time.
