I added Darklight and am using Thumbgen. How do I add more movies? Play list updating?

So I added about 104 movies but when I went and used thumbgen manually to add one more it didn’t update my playlist .

How do I refresh the playlist so it will show the new movies I added?  I added one but it still said 104.  

See if the following link helps.

Clear your media library.

Setup > System > Media Library > Clear Media Library

If that doesn’t work, delete the “.wd_tv” folder from any drive that you have attached or shared.  Then clear the Media Library
