JwPlayer and protecting Videos from being downloading
I'd like to know if JWPlayer protects the videos from being downloaded, I mean, because there are a lot of firefox Addons which allow to download videos with just playing it, but I found this page Tutplus.com, they use JWplayer and addons like the popular "Download Helper" and "Flash Video downloader" of firefox doesn't work to download it, is JWplayer giving this option? if it's not, what do you offer to protect the videos to be downloaded?
this is a link from that web using jwplayer
thanks for helping.
