JamPlay - Ripping from jamplay.com subscription service

[Extremist]

Hi, I have this guitar tutorial site I want to download/record videos off (.mp4) and of course, video capturing is not allowed (confirmed it with the support service). It requires membership first so that I can view the premium videos which the downside is linking to my Paypal account therefore if they found out I have been ripping their videos I'm dead. However, they said that I can use VLC to stream the videos provided that I don't save any of it. My questions then:

1. Can they trace me back if I download? What about record?
2. After streaming on VLC, is there a save function?
3. I doubt that they will know I've saved the vid on VLC (if answer to question 2 is yes) since it is already in my local drive. Can somebody confirm this?
4. Is violation of their terms of usage enough to penalize me with civil or criminal punishment? Or just termination of my account?
