I want to write a script to download all Walter Lewin lectures from this page in wmv format: http://videolectures.net/mit801f99_physics_classical_mechanics/
However the links to the wmv file for example for the first lecture: http://videolectures.net/mit801f99_lewin_lec01/ change when one reloads the page.
So is it possible to write a script which downloads the lectures one after the other automatically in wmv format. How can one do this?
wget -A wmv -r http://videolectures.net/mit801f99_physics_classical_mechanics/
httrack "http://videolectures.net/mit801f99_physics_classical_mechanics/" -O ~/VideoLecture "-*" "+*.wmv"
both didn't work.
