How to only see the video file with WDTV live


I have a WDTV Live with latest firmware…  I have a video file and .jpg files for movie title and one that says folder in each folder…  When I go to play the movie in thumbnail mode I have three image files to choose from two .jpg’s and one movie file…  All have the same .jpg image…  It is hard to see the extension so I would like to only have the movie file show up with a image on it… Is this possible?    Thanks

Are you files located in an external drive or in a NAS?

Add a period in front of the .jpg’s name
