Hey,
Anyone remembers that invalid motion vectors could have made xvid crash?
And that I wrote a fix for that, which clips MVs to valid range?
Well, it appears that DX50 streams do have motion out of range
sometimes. The clipping b0rked them, because when the vector was
clipped, this affected other vector's predictors.

I just changed the clipping code - it works just like before, but
doesn't really change the vector, just a local copy of it.
:)
