initially I was having problems with random videos (the same ones every time) not displaying the thumbnails, the issue had nothing to do with a specific file type, as it appeared to be random and the problem was only with videos, not pictures. after awhile of getting sick of this problem, I rebuilt the video cache which restored the thumbnails for about 50% of the videos which werent displaying which was good enough for me. although a few weeks later (this hapened shortly after upgrading to the newest version of VLC which may or may not be related) and now 100% of the videos are not displaying thumbnails. I have tried rebuilding the video cache by letting windows do it, as well as manually. I have tried updating shockwave, java, video codecs, and drivers. does anyone have any ideas of how to restore my video thumbnails, this has me completley stumped. :confused:
