I have tried everything!!! I've used Nero with DVD-R and then DVD+R Then I used Alcohol 120% with both DVD-R and then DVD+R Absolutely nothing works! Swap Magic 3.3 just says "NOT A VALID PS2 DISC" every single time!! If this has any relation, the two games I have tried are: Metal Gear Solid 3 and Ratchet and Clank Up Your Arsenal. PLEASE, I REALLY HELP!
