Guys and Gals,

Before any of you go to the work of researching and solving this 
question, let me say that I have already solved it.  Or rather, 
Google solved it.  Seems this is a more common problem that I 
thought.  I had to go into regedit and delete the upperfilters value 
and the lowerfilters value.  Doing this brought back the DVD to "my 
computer" and a simple uninstall and reinstall brought back the 
CD/RW.  Next time I will do the research before asking.
