been tryin to capture dv from my sony digital8 handycam video cam. i plug a dv adapter onto my firewire cord, then plug the dv into my camera and the firewire into my computer.

ive tried both microsoft windows movie maker and winDV to bring in the dvd video. it comes in great, not choppy or dropped frames but it appears like theres static or grainy all over the picture. like its not smooth but grainy/staticy/hard to explain. you can still see the whole picture, its just that its not smooth? anyone have any clues what it is and how to remedy?
