"Camera movement" - Problems

I've got a small project which is an intro for one of my DVD menus. It's made up of some jpeg files showing the Earth, the Moon, and some other planets. I try to animate the sequence with the help of pan and crop, adjusting the size of the screen on the timeline to "mock" some camera movement. The background, as you may have guessed is full of stars, but I've noticed something. In one of the sequences, as the camera goes from left to right, from wide to zoom, there are some "dark movement" behind the stars. I just wonder if this is a kind of interlace flicker or something. I've tried almost everything and the final result is always the same. After resizing the screen (not too much zoom in the sequence)...the "dark movement" was a little reduced. Any ideas????
Thanks in advance.

Likely a shift in the black gradient. Are you seeing this in the MPEG or in the avi? External monitor or computer monitor? Might well be that the stars are making the blacks appear to shift when they're really not. It also might be interlacing artifacts. Are the stars a still too? Or are they generated media?
If it's in an MPEG display, try dropping the Sony Restore Black filter, set to the Streaming preset. (It's the only one, I think)

Thanks for taking time to respond.

- always happens with MPEG (AVIs are perfect)

External monitor or computer monitor?
Both show the same problem. It looks like as though there were horizontal black lines going up and down, covering stars on their path, as the "camera" moves from left to right, from wide to zoom.

Stars and planets are stills, part of the same JPEG file.

Thanks for your help ;)

Checking <reduce interelace flicker> only "seems" to fix those dark lines....but I guess there could be some other option to fix this....Anyone?
Thanks!
