As I remember previously we can download the webinar videos as *.wmv format, but now it seems that we can only watch the videos online. Everytime we wanna watch them, we have to fill in the application form with a lot of compulsory (*) input.
In my opinion if you have a perfect network, you can try to record the webinar with some screen-record programme.
"Alternate Stress Case" is a quite good webinar which is worth spending time in working on it.
