Quicktime Pro problem

Hi, I'm new here, hoping to find an answer to a dilemma!

I'm running Quicktime Pro player 7 on Lion.

Some background: I'm making an animation of scientific data for a scientist, using Cinema 4D. I have two image sequences from the scientist to use in Cinema as textures to map onto a plane (in this case two planes side by side). The data shows two different qualities measured in the same sample of water. One shows a lot of color data changing over time, and the other shows mostly blue, then some color data. Both movies have a grey line running through them, representing a certain thing in the water, and it changes over time. The line is the same for both. Both of these movies will run at the same time, and although the color data will be different, the gray line must be the same at all times on both movies.

But the two movies do not sync up. They both start and stop at the same time, but after a while if you stop them, the gray line is different when it should be the same. Both movies run at 6 frames per second. Both movies have 201 frames. Both movies last for 33.5 seconds. When I open them both in Quicktime Pro, and run them by choosing Play All Movies, they run at the same time, but they are not the same when you stop them, and you can see that they don't sync up when they are playing.

I've opened the two sets of images (all 201 frames) and compared them side by side, and the grey line is consistently the same in every frame, but the movies don't run perfectly in sync.

Does anyone know what could be happening here, and what I can do to remedy the situation? I hope this description isn't too confusing.

thanks,
Jack
