Flv has lines after publishing

I have flv’s on a site, the originals were Quicktime.mov’s I encoded using medium Flash8 400. After the encoding both in test movie and from my server the movie playsback with lines throughout even worse on pan or zoom shots. So I encoded in 700 and the result is the same. If I playback the original QT movie in QT it looks really clean. I need to have the swf display an flv on the page. Any other info you need plz advize

any help?
