Digital BW, The Print

I have tried using the the CS2 "merge to HDR" procedure and both the prints and the screen 
images come out rather flat.  I, also, notice that the final merged image comes out at 72 ppi, 
while I started with all images at 360 ppi. 

 I researched the archives and I did not note that any body with happy with their results.  

There is the Photomatix software, at http://www.hdrsoft.com/ that says that images from 
their software does not have the same problem.  Has anybody used it, is so how are the 
prints?
