Is there a way to make FPDF/FPDI or Zend_Pdf support the parsing of PDFs greater than 1.4?

Question

I am trying to add an existing PDF (created otherwise) to a PDF created with FPDF using FPDI. It seems to work find for most PDFs, but I get the following error:

<

You can use FPDI with TCPDF, it will generate and read (with FPDI) version 1.7 PDFs.

See TCPDF - PHP class for PDF.

EDIT

I have recently been challenged with the issue of using various versions and formats of PDF with FPDI and TCPDF, and I can confirm that PDF versions above 1.4 are hit and miss, the interesting thing is that I have a lot of working 1.7 PDFs, and works about 50/50 on 1.5 and 1.6.

I worked around the issue by converting all non-workable PDF files to v1.4 using GhostScript which you can exec from the command line. Use ps2pdf14 from the GhostScript lib folder.
