DTBook->DAISY3 fails

I have a large file that comes out of Word. I want to get a text only DAISY book and the "Save as DAISY" full pipeline in Word takes a very long time because of the mp3 file generation. The "obvious" solution is to save the Word doc as an XML file and then run one of the DTBook->DAISY 3 text only translators. The XSL one specifically says it doesn't handle math, but the other should. However, the other translator dies in generating the SMIL files (can't open output SMIL file smilFile1.sml, which indeed doesn't seem to exist). In addition to this, it appeared never to run MathDaisy so the document would be invalid even if it did finish running (I think the SML file generation has to come after running MathDaisy). This was with whatever the current download is on April 9, 2010.
