Raw Data / Pre-recorded Information in Lead-in



Hi all,
I am writing a VB.net application. And I am searching a solution to protect the CD from copying.

An idea get came to my mind: When I opened Nero DiscSpeed 4, each DVD has a specific set of “Pre-recorded Information in Lead-in” (or RAW DATA)
can I use this information to protect my software against copying?

For ex: I should do a function that read this Pre-recorded Information in Lead-in, and compare it the value stored inside my program. If the comparison succeed than run the application, else exit.

If yes, can anyone provide me the function that reads the “Pre-recorded Information in Lead-in” exactly like Nero does?
