Hi all.

I'm a real newbie to all of this, so bear with me :)

Background: My office has paid a video group to create a short movie for us and to the provide us with the MPEG-2 and AC3 files, which I am then combining with a DVD slide show through DVD Studio Pro. Essentially what the folks who asked for this movie wanted was a movie and a "power-point" slideshow with no unsightly transition... I've given them that, but I'm having some trouble with the video itself that I need help to track down.

What's going on seems to be "line twitter": horizontal borders of high contrast are shakey. I know the supposed solution for this -- make sure that your field order is correct all the way through. I have tested the DVD with both orders and the emulation looks the same on both of them. I have only burned the DVD with the field order being automatically detected; it looks fine (doesn't twitter) on my Mac and it also looks fine on the big plasma-screen we have next door. The flicker is downright painful on a regular old TV (my apologies, my terminology stinks) and even worse using InterVideo WinDVD to play back on a Windows XP machine.

Anyone have any idea why the twitter only seems to appear on certain machines? Any idea how to fix it? I don't have access to the original project to export the video myself (they use Avid, I believe, I have FCP), but I can request that they export it in some other way if anyone thinks that that might fix the problem.

If anyone wants some specific information, let me know. I wish that I could provide you all with an example, but that's outside of my control.

Thanks in advance!
