Need a little more information.
How did you capture your footage? Did you use firewire or usb or even analog? Also I know others will want to know what kind of set up you have. Did you defrag your hardrive before capture? So many variables etc.... Sorry :(
If using USB or even analog there is a possibilty that you have some dropped frames causing the skipping maybe but I will leave that advice to more experts than I.
