Just try to develop an application around cdrtools and dvd+rw tools- you can find the code for both freely available. You ca use either Cygwin or Mingw to transfer the code into Windoze.
Burnatonce made a bad decision, and discredited cdrecord in favour of CDRDAO. Unfortunately enough CDRDAO got messed in a very complex licences issue, and it's development has stopped for more than a year ago. Rewriting the whole BAO code, so it would use cdrecord instead is extremely laborous, but IMHO Jamieo (the BAO developer) should do it at some time, even if it has to start counting from "BAO-new 0.01"...
dvd+rw tools is a relatively new Unix project, which can be ported into Windoze- if this is done then nobody will ever need a commercial DVd burning app.
