Combs on moving edges

I have an AVI file captured from DV camera (using Vegas Video, PAL DV). When I import this file into the timeline and play it there are small stripes (like combs) on moving edges (they look as if even lines are light and odd ones are dark). The same problem is with MPG file created from this project. At the same time I have no problem using this AVI file in the Pinnacle Studio 7 (both playback and MPG file (created by Studio 7)). In both cases the MPG files were played using Windows Media Player.
When I rendered this project directly to the tape all seemed OK.
What should I do to solve the problem?

Thanks

That article explains why it happens, but question is how do you fix it? I have the same probelm. I am just trying to print to tape (mini DV)and when I play it off the tape onto a normal NTSC TV the lines in the video are really bad.

I imagine I have to change some setting with:

Lower field or progressive scan...???

there is definitely something wrong then. you shouldn't see interlace lines on a normal non-progressive TV. how are you capturing and printing back to tape? if you are capturing via Firewire, then the field order should be set to "lower field first" on the media as well as on the project.

The problem with preview: the key is to preview as half original size - it is perfect :-)
The problem with MPGs: I have made a new post on this issue.
