PAL to NTSC

[blazin121]

I have this "Half Life PAL CDrip"
I burn it on cd with Nero, I ran PS2 fine ( I have modchip )

just when its at the Half-Life's loading screen, the screen is flashing from down to top again and again really fast, same thing goes to after wards

I guess its that my 50 inch TV is NTSC

so whats a way to convert it? ( I didn't find a patch to convert, I only fround NTSC to PAL patch on megagames )

thanks
