Well, with everything you've just said, the burn SHOULD in theory work. The only thing I can think of is a bad rip. Try re-ripping the game from the original disc using the 0800 fw and it will hopefully be able to play. I have 2 backups of this exact game and neither one had any issues. Then again, I have an iHAS 224 rebadge flashed with BurnerMAX, soooo... Yeah. Try another rip. =)
Also, you don't need to be connected to LIVE to flag the console, you just need to insert and attempt to load a game that doesn't pass the AP checks. That said, if that was the case, the error message you would've gotten was "Unsupported Disc", not the dirty disc message, so you should be fine.
