Timelock CD's

I need to put a simple time lock period on CD's that we create in house. I need the CD's to run for a specific time period (say 4 weeks) and then not operate any more. These are for use with people that are not at all likely to try and hack them, they are barely computer literate at all. It needs to be a simple piece of code that we can put on the CD's (mpeg format) as we create them. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on Windows platform. 3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site). ## Platform Windows 95/98/2000/Xp/Me
