Mokey tracking issue

Hey all,
I was recently trying to composite a shot for a music video where we rigged a camera on a track dolly (straight) and dollied past a series of paintings. The idea - place our lead singer in the paintings (composited green screen footage where the lead singer had many different looks (cartoon, posterized, line art, etc.).
So, there's the idea. I started to track the video dolly move and drew a rough shape around the main painting. The timeline was directly in the middle so I started tracking forward then backward. I adjusted the clip +2 pixels for all four sides of the clip framing. I tracked position, scale, shear and perspective. When the painting gets 2/3 off the screen the track starts going completely haywire! I cannot seem to get to Mokey to track this fluidly either way. The rough shape is basically the shape of the painting frame with maybe about a 3-4 pixel area wider than the frame on all four sides.
Can someone please tell me what I am doing wrong? I adjust the lens setting to make certain there was no lens distortion and all I wanted to do was to send the tracking data out to Shake and composite the individual singer shots one by one as to make certain the tracks were adjusted perfectly for each shot. Thanks in advance and I look forward to hearing/reading your response.

You can send me a link for both so I can see what you are doing and I can also try to give you an idea of how to best handle the shot.

I emailed you my mokey project file.
try this out. What I did was start the tract from the first frame (465 I think) and draw the track shape around the edge of the frame. I then tracked forward and every 20 frames or so as the artwork came more into the frame I would stop the track, move the two points on the left to cover more of the art and continue tracking. I would do this until the shape was the size of the artwork and then I would just let it keep going.
One important note, I don't know if you did this or not, but in the camera or clip tab, depending on which software you are using, you need to adjust the edge of the frame to remove the blanking lines. They can throw off your track a great deal as they stay the same but the rest of the image keeps moving.
