Hacking Screen tearing in ps2 games Webman

[Wheelkirby]

I've been playing ps2 games on my slim ps3 thorugh webman and it works perfectly except for 2 games Ultimate Spider-man:limited edition and spider-man 2
for some reason this games have a weird sort of screen tearing at the side of the screen but only during cutscenes weirdly i have no idea what causes this, any ideas?
