mmmm... If I recall correctly AVIStreamXX from MS
doesn't work too good with XviD's VFW (not propperly
registered, nobody knows how to do it right, MS
doesn't say)

Also check your bitmaps are propperly aligned.
Check that you're using the latest CVS snapshot rather
the latest stable release.

I can't say much more to you, but if VirtualDub is
working for you, then you must be wrongly using XviD
within your code (by debugging... where does it
crash??), poorly managing the bmps, or MS' AVIStreamXX
may not be the ideal solution.
What is the bpp of the inputted images? Colorspace?

Why don't you try the AVI input/output sample from
xvid_encraw and see if it crashes, I believe it uses
the same interface.
