You can't just burn and play it, not even with a jailbreaked PS3. It has already been tested and failed. You´ll need a PS3 with debug firmware to be able to do anything at all with these pkg-files. On the other hand, I don't know if they can be converted somehow to something functional for those with custom firmware. Possibly. Correct that there is no copy protection. The press kit disc can be copied with no problem.
