Magic 3.1 DVD Movie playback ?

[Don2050]

Hi,

I searched the forums but did not see anyone with this question....

I recently put a Magic 3.1 universal modchip(The blue one with the smiley face on it) into a v5/v6 PS2. All the games both CD-R and DVD-R work fine....however, I can no longer play DVD movies only. Even commercial DVD movies do not work any more, it just says 'Please insert Playsation 2 format disc'. I know this unit could play the movies before the modchip. Has anyone seen or heard of this before ? Any insight would be greatly appreciated

Thanks
