dvipdf does not work

Dear All,

I know it is a R list but please let me ask a question about dvipdfm.

In latex, the command dvipdf file.dvi generates a pdf file. When I use the
beamer.tex file, the output has different sizes and the slides are not
suitable for presentation. The dvipfm produces slides with correct sizes
but some parts of the equations are cut off.

Should I install some program to dvipdfm works properly?

The pdfm does not work well with beamer files?
