First let me say hello and thanks a lot to all you contributors, i have lurked here for a few weeks (a few weeks ago i knew nothing about burning ps2 games) and learnt lots of extremely useful stuff - i have burned loads of ps2 games to dvd, no coasters. I have a v3 ps2 and swap magic 3.3 with slide tool. My problem is with cd games - some burn fine (maximo, marvelvscapcom2), but a couple of others (worms forts under siege, snes station) give me a 'not a valid ps2 disc' after swapping discs with swap magic. I have tried alcohol 120% and also dvd decrypter. Probably I think it is my media (memorex 52x, kind of blue/greenish bottom)- but i have had problems finding out which cd is best for ps2. Any ideas? Thanks in advance.
