ha, as if your ever going to be able to burn 4525MB onto any dvd5, your in a dreamworld matey, - this is assuming you count 4370MB as a dvds capacity.
Even if you measure it in the way dvdshrink does, whats that like 4482MB? No chance....
Why must it be sony media?
(sorry for rudeness, I talk like this i'm not really being rude, a little surprised)
