I've found some troubles in visualizing MOSEM didactic movies in this folder:
http://dydaktyka.fizyka.umk.pl/MOSEM/moviesthe problem is that all documents contain a crypted microsoft codec wich is not installed on a lot of desktop's in my school and make movies not visible nor using vlc nor using windows media player.
when WMP fails, the user is redirected in
this way on to the internet, and a codec is downlodable, after few other steps, accepting a funny eula.
Offcourse, the same happens at home for more students. A teacher has this problem on his own apple laptop, too.
to avoid the issue, I suggest to convert movies in a standard format, such as in
this example, which works in windows98, too.
