Looking at the response headers, there are only a few differences: the 
direct download from the server contains a header "Accept-Ranges: bytes" 
which allows the browsers to restart a download or to skip forward. The 
PmWiki's protected download feature does not provide such a function, a 
file is served at once, the browser has to download it linearly.

If you remove or comment out the line

   $EnableDirectDownload = 0;

from your local configuration, and fix Apache .htaccess permissions, it 
will probably work.

OTOH if you have disabled direct downloads, you probably have a reason 
for this.

Alternatively, you may define and use an InterMap prefix to easily link 
from your pages to a directly accessible directory (or symlink) on the 
server, for example:

   # in the page [[Site.InterMap]]:
   Videos: /~paul/Videos/

where on the server the Videos directory is a symlink to one uploads 
subdirectory that may be accessed without passwords.

In content wiki page:


See http://www.pmwiki.org/wiki/PmWiki/InterMap for more information. 
Your authors will still need to upload the videos the usual way.
