What settings did you use when uploading the bvh - all the dialog choices like priority, loop in-out, etc.?

it makes no difference. identical results, no matter what settings used for upload. see attachment: bvh upload variables.png

Could this be caused by the optimization applied to bvh uploads? Ref: BUG-309 & VWR-16277

As Whirly notes, this is probably related to the bvh optimization pass. Because of the additional processing done on bvh files, there is no guarantee that bvh and anim will give completely identical results. I'll take a look though.
