Hi again,
Not knowing what exactly your issues might be, I took a guess and assumed you encountered the same issues I was having. That is, some requests are being actively blocked since they appear to be automated. I've uploaded a new version of Jav-It which simulates all requests to appear as a browser. Please give that version a try and see if it fixes things! If it does not, please send me the information I requested above and I would be happy to try and debug this with you!
Note: This new version of Jav-It has functionality broken down into categories (For when new features become avaliable). So to run your scan simply type the following: "jav-it.exe catalog -d <your_video_path>". Note that the only command avaliable right now is "catalog".
