PS2 expects a DVD with ISO and UDF filesystem. Crappy Winblows Joilet/Romeo discs won't do it. A good idea is use Nero and set it up to burn as ISO/UDF (It has that option so it must work just fine if youi set it up right.)
If the disc has wrong format the PS2 will refuse to read. As the others stated burning speed and brand media are also vital for sucess on this.
And the "Burn as DVD video" thing works because the DVD video filesystem is also ISO/UDF.
