i had a tv show on vhs and i captured it to my dv camera

canon optura 10

and then with a firewire i captured it to premiere 6.5, edited it and convered it to dvd, authored it w/tmpgenc dvd author and then burned it

i noticed that when i captured it the video was kinda shaky, i dont understand why/how it does this. and how can i fix it (if possible)

on the original vhs the video is fine
