that will not work on windows because of this bug:


according to IOhannes this has been fixed in the sources already but you 
would have to compile Gem on windows yourself. i didn't succeed at it 
and it's probably nothing  you should do while a class is happening.

so, for this we have to wait for a next official windows Gem release ...

yeah, thought so ;-(

this means mjpeg codec is not supported natively, you will need some 
codec pack to be installed in windows.

i tried without success to produce an "indeo" video with ffmpeg. this is 
the codec the "homer.avi" video uses.

"wmv" can be played by [pix_film], but only on "auto 1" mode, frame 
messages don't work. same for mpg files encoded with "mpeg1video".

sorry, but i guess unless you can install codecs on your student's 
machines you are probably out of luck here, unless someone can prove me 
wrong ...
