Nuances in the generation power of LaTeX mean that it is nontrivial to produce PDF files and DVI/PS files from the same source. This is because pdflatex (which produces PDF files as output) does not accept the same set of graphics formats as input as does latex (which produces DVI files).

Therefore, in order to produce PDF files from LaTeX source, it is necessary to either (a) Buy Acrobat Distiller, which allows you to migrate PS to PDF, or (b) do this for free with GhostView. You can then either change all of your images to PDF and use pdflatex, or change the final output to PDF from generated PS format.
