Help dumping PS2 games?

[SuperMario123311]

So a friend of mine got a rare Namco Demo Disc which happens to have a beta of Pac-Man World 3, Which we want to dump. But so far any ISO dumper has been unsuccessful. Please note I am looking for free ones and most of all: Fully trustable/No virus-infested programs.

Cyberlink ISO and DVD Decrypter have been rather unsuccessful.

Does it use a filesystem that is readable by your system? Most PS2 games are readable in Windows.
