Synchronization in MLP

I have been playing with the MLP for a while. I have had no problem taking the animations from other pose ball sets and putting them into the MLP. It seems that whenever I put animations from other pose ball sets into the MLP, the animations are synchronized when I use them. I have thus assumed that the MLP performs some sort of magic that takes care of synchronization.

I have finally started getting my own custom animations almost finished. I uploaded two last night that are meant to be used as a synchronized pair. However, when I put them in the MLP, the same way I set up any other animations that I might have taken from other pose ball sets, my custom animations do not synchronize.

Each animation of my set was created in Poser 7 and exported to bvh. Each was 121 frames; the first frame in each is the reference frame, with the actual animation on frames 2-121. The speed of each is 15 frames per second. Individually, each previews as just fine appears to run as expected in Second Life. The problem comes when I put them together.

I was wondering if there was anything in the upload options that affect synchronization. The options I set on each were: Loop checked, 0.00 to 100.00; Priority set to 4; Ease In at 0.00; Ease Out at 0.00; Hands Relaxed; Expression Kiss.

Help or tips would be appreciated.

The syncronization problem has nothing to do with the animations but is caused by each of the two seperate animations starting at different times. The only way to get them to syncronize is to modify the MLP scripts to simultaneously restart both animations. Even this may be affected by lag issues and they will tend to drift out of syncronizations over time so a periodic resync may be needed. I believe this is how many of the couples dance balls operate.
