Just don't forget -- it's even easier to install desktop-recording software.
I agree. However use of desktop recording softwares is similar to using an audio recorder to record a song on the radio. We cant do anything about it The main aim was to remove the download capability of the ubiquitous downloading tools/plugins (like FlashGot, DownloadThemAll, VLC etc) which mainly use the video saved in the cache. So far we have been successful in that. Ideas to avoid recording via a screencam, anyo…
I guess that kind of makes the point. If you can't stop it being recorded, what does the encryption serve? If it is content that is worth anything, it will be screen capped and pirated within a few hours.
Are you just hoping to serve adds every time a casual user wants to watch a video because their simple download tools dont' work?
