FCP problem that defies logic

Ok, I've got a huge problem in FCP and need some expert advice:

A little background: we've been editing a short (around 25 minutes) on FCP 5 for the past three months. we recently bought some new Macpro towers and so had to upgrade FCP. Ever since then we have been experiencing some weird stuff, but the biggest problem is the following:

When we shot the film (at night) in one scene, there was a window in the background. A number of cars drove by while we shot and the director didn't seem to care then, but now wants those passing lights gone. Well, the first pass was to use a garbage matte, along with a still on the shot without the lights and cover up the passes. good try but not perfect, we could still see some remaining stuff. so i took another pass at the problem and also used a garbage matte/still combo and created a better matte that we are all happy with.

Now this is where it gets weird. i have since erased the original mattes and exported the footage. the quicktime export looks great, but when i convert that to an m2v for dvd all of the sudden, the old mattes are in the shot and we can see the car.

so, can anyone explain this or give us some advice?
 
Just to clarify...

(1) You did your visual effects work, that you were happy with, and exported a self-contained Quicktime movie file from Final Cut Pro.

(2) You then watched/checked that movie file and the visual effects in it are clean/to your satisfaction.

(3 You then imported the self-contained Quicktime movie file from (1) into Compressor (or BitVice, or whatever compression program) and made an mpeg-2 from it.

At this point, when you review the MPEG-2 you find that the visual effects are not infact the signed off on ones, but instead the unsatisfactory original attempt?

cheers.
 
You got it.

I'm attempting to rebuild the dvd making sure to not reuse the VIDEO_TS files, but I am worried that i already did that.
 
Yah that does defy logic. On first glance of your post I figured render file issue. Just dump all your render files and try again, but now from you confirming the workflow I wrote, the render files shouldn't be an issue. I don't get it. I think this is a good one for BenB to tackle.

cheers.
