video is jerking on computer monitor and not on TV screen

[Giuseppe Mangione]

I’m editing a DV Pal video and I did some movement with some still images. When I edit the file on FCP, I watch the output in a TV monitor screen and all the still images movement are fine and smooth. As soon I export the whole file and watch it on computer monitor I get some jerking in all the still movement.
The file will be screen on a projector, where you can see as well all the jerky images.
Any suggestion?
thanks

What codec are u using? What compression is ur timeline?
What hard drives are you playing the video off of?

The timeline is a DV PAL, and I exported on the same format.
Then the file needs to be played in a PC laptop. But I don’t know the characteristic of this laptop.
It could be something that as to do with the codec? And that the computer cannot handle it?
