Video Lectures DVD Locking and Protection

[sharjeel]

 
Dear Members
I am lecturer physics in college and I want to make my lectures dvd which is the best software to lock my data so that it cant be copied and no one can also make its image   in short no copy by any mean only users can view it
Thanks

#1 on the Google hit is: http://www.fortiumtech.com/patronus_dvd-anti-rip-copy-protection.aspx?gclid=CNvSur-lrrsCFbA7MgodnXUAvQ

I have never worked with protecting media from easy duplication, I have only worked with writing programs requiring activation keys to function and those too are not immune to cracking with determined software crackers.

Biggest problem is that this DVD copy protection still does not protect from someone using a program such as FRAPS to capture the audio/video of this and having a copy of this, or AV capture device over HDMI etc to make a copy!
