I'm eager to try the Movie-JPEG format, but I can't get any MPEGs 
converted to Movie-JPEG.  The problem isn't the JPEG plugin -- I 
can't open any MPEGs!  I know that I used to be able to, but in a 
completely-updated 3.2 image, running the 3.1.1 Mac VM (not OS X), 
every MPEG or MP3 file I try comes back as being invalid MPEG.  These 
are files that I can successfully play in QT Movie Player and in 
iTunes.

I've been wondering if I even have the MPEG plugin -- maybe the 
primitive is bombing because the module can't be found.  I've tried 
downloading the MPEG plugin from www.squeak.org in the 
3.0/mac/extra_files directory, but with the same result.

Some questions:
- Is there a more recent MPEG plugin somewhere?
- Is the MPEG plugin built in to the Mac VM?  How can I find out?  I 
know that there's a way of getting an array of all the available 
plugins, but I can't find it anywhere in the image.
- Are there specific MPEG versions that work or don't work?
- Can anyone point me to valid MPEG files that Squeak can read that I 
can try this?

Thanks!
   Mark
