Hi everyone
first of all, sorry for my poor english.

Now I have problem with video input, LFG card

I live in NTSC country

29.97 / 30 fps always looks jerky
It looks like pulldown error when they are jerky
It happens every 4-5 seconds

25fps looks okay
My friend with gtx card, 2010 mac has same issue

FPS 24~60 tested

10.6.*
10.5.6/8 tested

Thank you
