alright heres the scenareo: I have some .ogm files and I used virtual dub mod to convert them to a file in which i could import into windows movie maker 2. I used the "div x 5.1 .1" codec, but there was a flickering line at the top of the video. And I did not like that.

Now i'm not sure which of the following codecs I should use now. It takes forever to convert the episodes, so I dont want to do trial and error, and then find one that I like and then find out later that something like the image above happens during the video every minute or so.
here are the codecs that i can use (the last one is x vid):
