Soul Calibur V XBOX360 Error

Dashboard shows Soul Calibur V Logo but when I click to play I get “Disc is not supported” screen.
Same happens with Metal Gear Solid HD.
Both were burned using imgburn with “Layer Break – Calculate Optimal” and “truncate image” mode.
Answer #1
Which firmware and dashboard are you on?
Answer #2
Dashboard 2.0.13604.0 (BK:2.0.1888.0)
I think I have iXtreme 2.0 (Liteon drive)
Previous games work btw.
Answer #3
LT 2.0 is your problem =) You need LT 3.0 firmware to play the latest games.

OK, Thanks.
