There is a tutorial on the forum how to burn it (
http://www.ps3hax.net/showthread.php?t=13247 ).
Those 2 folders (PS3_GAME, PS3_UPDATE) that are inside of the root folder of the game, and that 1 file, put on the root of the disc and burn it slowest as you can.
Lable of the disc doesn't matter, but i prefer to call it like the game id was (bles/blus etc).
But wait for the package that deank was mentioning.
