Converting JPEG-scans or DjVu files to PDF
1.1. DjVu2PDF - First approach
Use the program STVU Converter (rar password is vitki.net)
1.2. DjVu2PDF - Second approach
Use some DjVu viewving software and a virtual PDF printer.
Detailed conversion steps:

2. Download and setup a free PDF virtual printer, for example PDF Creator (description).
3. Open your djvu in a viewer (windjview) and print it (Fig. 1).

7. When PDF is saved, you can open it in any PDF viewer, e.g. adobe reader.
If you install PDFCreator without asking, the program installs a program called PDFforge toolbar. Afterwards, if you get a 404 error (webpage not found) when surfing the web, the PDFforge toolbar hijacks your browser and automatically redirects you to urlseek20.vmn.net using mybrowserbar.com. To fix this problem, go to Add or Remove Programs and uninstall “PDFforge toolbar.” Luckily it’s that simple ... Starting with version 0.9.7, PDFCreator has included a new toolbar application, PDFForge Toolbar (versions prior to 0.9.7 have a different, optional toolbar called "PDFCreator Toolbar"). Users have reported that this software changes their computer settings. PDFCreator's end-user-license-agreement states that the software will "modify your Microsoft Internet Explorer and/or Mozilla Firefox browser settings for the default search engine, address bar search, "DNS error" page, "404 error" page, and new tab page to facilitate more informative responses as determined by The Toolbar". All instances of "page not found - 404 errors" redirect to a search site that has been reported as causing multiple problems for users. The toolbar disclosure screen can irritate users, who think they have deselected the toolbar while not removing it from the list of installed components as stated on the screen. Some reviewers have termed the toolbar as "malware" and PDFForge has received criticism for including this toolbar with PDFCreator ... http://en.wikipedia.org/wiki/PDFCreator
