Don't use the speed change effect. If you need the clip to be slower, add in extra frames until it's slow enough. If you need it to be faster, cut out extra frames. Or do your speed changes in vdub - wmm can "read" speed changes better than it can "export" its own speed adjustments.

Open them in two minimized vdub screens - compare frame by frame. When you hit one of those sped/slowed clips you'll see the differences immediately - too many duplicate frames or not enough duplicate frames. You can use the 'direct stream copy' and 'append' functions to edit the dv-avi copy so the frames match the wmv version. Once that's finished and the two copies match frame for frame, your sync will match your original wav perfectly. This method takes an hour or two for a typical video, but it works every time.
You can play with speed changes, but doing a frame by frame comparison is the easiest and most guaranteed (though slower) way I found to get around that dv-avi sync problem.
