That's probably inaccurate.

Then I'll try to play a game burned onto DVD-R disc (Of high quality, like Verbatim discs) if the console is modchipped. This is because these burned DVD-R discs are darker than the original Playstation 2 DVD discs, and can test if your console's laser has a weakened laser emitter (For reading DVD discs).
Lastly, I'll try to play original Playstation 2 CD and DVD games.
While you try to get the console to play any of the discs, you should not see any of the games' cutscenes stutter, skip, and/or hear the console struggle to read the disc (E.g. you should not see a "Disc Read Error" message, and you should not hear any clicking sounds of the laser eye moving up and down).
Note: This "clicking" sound I've mentioned is actually much softer and higher pitched than the usual sound a laser would make when it's being shifted around the drive (Which is much louder and dull).
