epstopdf is basically a ghostscript call as well. Which version of
ghostscript are you using? Do you have different versions of
ghostscript installed at you maschine and they're interfering? The
font-problem you have in one case but not the other sounds a bit like
this ...

Just to clearify: You're always working with an EPS created by PyX?
Than you convert that in several ways and you get into troubles using
the resulting EPS? (Why not use the PDF output of PyX? Any troubles
with it?)

I'm kind of surprised, since I would expect PyX EPS outout to be well
well established and kind of stable. Anyway, I would first try to
translate the content to a positive bbox. For small figures the most
easiest way is to set a paperformat by

    c.writeEPSfile("test", paperformat=document.paperformat.A4)

and the like. If you look into the EPS the bbox info at the beginning
should now be positive in all parts (when your fig isn't too big). BTW
you can now also just print the EPS on a PostScript printer and the
result will be centered on the page. We do know of some cases, where
negative bboxes lead to stange behaviours although they should
perfectly work.

In case you're doing something else or it doesn't help, feal free to
post some more details or even an example somewhere on the web (this
list is limited to 40 KB per mail) ...
