I have implemented many enhancements and fixed minor bugs in PDFRead 1.8.1  (see post#1 above in this thread)
Changes in this release:
Changelog [2008-03-30] 1.8.1 (by NR)
• can now install PDFRead to a different drive than your C: drive; just keep the same subdirectory structure for the GUI options file to be loaded properly.
• now uses, as a default, the input filename as the output filename (without file extension).
• added .prc output format support using opf2mobi.exe from Mobiperl by tompe on mobileread.com.
• added .cbz/.cbr input support for Comic books using unrar.exe and creating a (sorted) list of image filenames.
• tweaked and added Profiles for PRS500, PRS505, PRC-Mobi (Kindle and Cybook Gen 3), iLiad.  On REB1200 only provides a 2 pixel left and right margin to avoid bleeding into the edge of the screen.
     The default Profiles are:

        Note:  Profile appended with '-p' means portrait; with 'C' means Color.

• FIX: portrait modes now ignore rotation preference
• cover page used in resulting ebook now includes author in addition to title and TOC (if any).
• changed default category to 'PDFRead_Converted'
