I thought about this a bit more and thought of a solution to the 
problem.  I will rework the patch to run as a standalone 
application/daemon which can be a 32bit static-compiled app.  Mythtv can 
then pass frames back-and-forth using shared memory.  This should allow 
us to have a 64bit mythtv running 32bit windows codecs, and it is pretty 
easy to implement.  Look for an updated patch within the next week or so.
