Ripping videos off websites (batch)?

Hi guys,

I am going overseas soon and data roaming costs a bomb. I paid for the subscription to one of the e-learning websites and each page includes a Wistia hosted video. May I know if there is a way to BATCH-download all these videos at once? I tried httrack/website copier ripper and it didn't detect the videos. Video download helper works, but i need to play each video before I can download them.

What is the easiest way to download them for offline access?

Thanks!

does anyone know?

Tou need only videos, without content?
