Tracking export camera/ need help

[bagou01]

Hi, i need to track a scene, and i tryed boujou, syntheyes, and voodoo, but i always have the same problem: in the tracking software,everything runs fine, the points tracked are really correct and stick to the frame, but when i export, my camera in lightwave shakes sooo much more and the tracking is completely ****** up. either boujou or syntheyes, the result in lightwave is completely different that the one in the track soft.
i tryed to export in 3dStudioMax and i don't have that problem, so it comes from my lightwave export.
anyone has an idea why my camera movements is so wrong in LW compared to boujou or syntheyes?

well i found the issue, the tracking software synchronised to frame 0 and LW sync to frame1 i sticks now,but is still not completely perfect, the points slightly move away from their start position, from the begining to the end of the shot
