The video is recorded as interlaced and you will see interlaced  
artifacts on any progressive display. The only way to prevent it is to  
run a deinterlacer on the video which guesstimates the missing info  
between the lines and presents that along with the original video. You  
can either do this at playback time or you can transcode into a  
progressive format with deinterlacing turned on, but I've never done  
that. Of course, the other option is to only watch the video on an  
interlaced display in which case you do nothing and it will look just  
fine.

In other news, my dictionary didn't alert me that anything was wrong  
when I used the word "guesstimate" and that makes me a little sad.
