BCC DVE Aspect Problem

I have been using BCC AVX plug-ins for a little more than 2 years. There is an apparent bug in the DVE that has needled me & I wonder if this is a known issue. When I enable motion blur, shadow, & then move my image using resize or rotate, the aspect goes wild.

It can be corrected by scaling the X to 50%. Problem is on the last field of the effect it jumps back to normal aspect. No key framing will fix the problem completely since adding a keyframe on the second to last field will then give you a big motion blur glitch for that field.

I have seen this consistently on BCC3 & BCC4. I am not currently running BCC5 so I cannot speak for it.
