Greg already answered about how to do it right, I just want to give some
on what happened when you opened those PDFs.
PDF is a complex format that holds text, vector graphics, bitmpas and more.
not intended to be an editable format but something like "electronic paper".
Nevertheless there have been attempts to convert PDFs back to editable
None of that works very well, let alone faithfully. Inkspace and OpenOffice
allow opening PDFs. Scribus can import Postscript and EPS graphics using the
ghostscript program. That same trick works as well for PDFs, but with not so
results, as you saw when you opened the PDF with Scribus. Therefore we dont
this feature. Opening a PDF in Scribus is very much like feeding a cut+paste
paper collage
with several layers into the automatic sheet feeder of a xerox machine...

The way to place PDFs inside a Scribus document is to create an image frame
and attach
it to the PDF file. Scribus will do a pretty good job in reproducing that
PDF in the final result.

About transparency: there's on/off transparency as realized with stencil
masks and clippaths
and there's alpha-transparency with translucent images. The first one is
supported by all
versions of PDF and Postscript, the second only from PDF 1.4 onward. That's
why you get
warnings from Scribus if you use that kind of transparency.
