I was wrong, and (no surprise) Aditya was correct.

The %macros=mkvi line is not needed in dm1.tex. It should be at the top 
of MyLayout.tex.

You may then reference MyLayout.tex (note the addition of the extension) 
in dm1.tex, or you may rename the file to MyLayout.mkvi, where you can 
reference it as either MyLayout or as MyLayout.mkvi.

Sorry for the noise.
