Not sure it its a bug or my setup


Hi for the last few months I have not been able to get the program to extract thumbnails from my videos, it used to work fine I have no idea whats happend as all I have done is added a few games to my system and a new AV prog other than that my PC is still the same. It's says its "Adding Thumbnails" but nothing happens it just carrys on as normal, Could it be a codec problem or the prog?? I have Vista x64 and version 1833
