Creating EPK with Video, Photos & Text Files

Greetings. In the past I have created effective EPKs that included videos and photos using DVDSP 4. However, I have a client who has sent me a ton of PDFs that she would like to have included and now I'm stumped on how to proceed. I've been searching for answers on how to include these files, but nothing has been helpful. If I include PDFs (or even convert them to JPEGS to be included in a slideshow) no one will be able to read the text as there is no option for zooming/enlarging. I know this is possible because I've seen these types of DVDs/CDs in the past. Does anyone have a recommendation for including these types of files in DVDSP or perhaps another software I could purchase?

Thanks in advance.
