I want to include PDFs of version 1.6 (or higher) as pictures in my document. First I got the usual version-warnings, which I got rid of by changing dvipdfmx.cfg ('V 5' to 'V 6'). So now a PDF is created, but the pictures are not included (the area just stays white). A MWE will follow soon. Including the pictures as version 1.5 PDFs works just fine, but this leads to a too large output file.
