I wrote a blog post yesterday about how to disable SSL automatically. I do enough P2V's that I got tired of doing it all manually. You can find the steps at my blog: http://www.vtagion.com/automatically-disable-ssl-vmware-converter/
Hopefully this will help some of you out. Let me know if this does.
***Note*** you must have write access to the converter-worker.xml file for this to work.
