1. Go to Pornpros.com

2. Select yout favorite Video via "Our Girls" or "Latest Updates"

3. Go to the Detail Page of this Vid

Example:
http://www.pornpros.com/episode/?episode=3387

4. Look at the URL of the Big Sample Preview Pic
In this Case:
http://cache1.images.pornprosnetwork.com/cms_data/DeepThroatLove/kaseychase/photos/sample.jpg-299x372crop

5. This is maybe a bit tricky:

You have to build your own url to access the protected content via the Cache servers
http://cache1.images.pornprosnetwork.com/cms_data/ *SITE-NAME* / *MODELNAME* /videos/ *MODELNAME* + "-wmvFullHigh-1.wmv"

So for the above example it would be:

http://cache1.images.pornprosnetwork.com/cms_data/DeepThroatLove/kaseychase/videos/kaseychase-wmvFullHigh-1.wmv

Or another example:

Detail-Page: http://www.pornpros.com/episode/?episode=3152
Pic-URL: http://cache1.images.pornprosnetwork.com/cms_data/MassageCreep.com/madisonscott/photos/sample.jpg-299x372crop
So your URL has to be
http://cache1.images.pornprosnetwork.com/cms_data/MassageCreep.com/madisonscott/videos/madisonscott-wmvFullHigh-1.wmv

Additional-Infos:

The Folder has to be "/videos/" instead of "/photos/" in the URL if you change the Preview-Pic-URL

There are a few more options:

as last part of the URL you can choose between

"-wmvFullHigh-1.wmv" WMV-HD (means not everytime HD but imho the better quality version)
"-mpgFullHigh-1.mpg" MPG-HD
"-wmvFullLow-1.wmv" WMV-LOW
"-mpgFullLow-1.mpg" MPG-LOW

But maybe not all will be there for every episode so you have to try out.

if your browser dont give you the "save as ..." window (like in my case with opera)
try either another browser (with internet-explorer works) or try a download tool like wget an so on

Hope you understand it, could be a bit tricky
And please excuse my very bad english

So if it works for you please rate/say thanks

Oh and perhabs someone coul make a greasemonkey-script or so???
