If user copy license file to other computers, the license is invalid. If user copies the encrypted file to other computers, user still need input username and password. So, don't worry about the transmission of the encrypted files.
Rights control Content providers could control the encrypted file rights, and set - how many times could the user play after purchasing. When your user opens the encrypted file, system will automatically deduct a sum certain money from user's account. The amount deducted is what you set for the rights.
There is no need to encrypt the file again if content providers want to change the rights of some contents.
