I have had this problem for a little while now and it's starting to bug me, Every time i put a new video that i publish or add to my computer doesn't have an image, just a thumbnail, i have tried multiple solutions like Deleting the Cache but that only got rid of my old video thumbnails too.
Folder Options and Switching the Default Program back and forth with no success.
The problem, i think, started when i uninstalled Nero Burner and i heard that this same problem happend to other people that did it to.
Please if there is a Registry problem or something i can do Please tell me.
If i don't have this thread in the right topic can a MOD move this.
