I have a list of movies in a folder on Windows XP (SP2 with all updates). When I have the view set to "thumbnails," there are 7 files that don't show the thumbnail of the movie, but rather the type of file icon. At first, I thought it was a codec problem, but the movies that don't display the thumbnail play fine. Then I decided to delete the "thumbs.db" file in the folder so it would refind all the thumbnails, but still those same 7 files don't display a thumbnail.
I used to have "K-Lite Codec Pack v3.10" installed on my computer, but it was giving me some problems, so I uninstalled it and installed "XP Codec Pack v188.8.131.52." The problem with the thumbnails, however, has been ocurring even when I had K-Lite installed. It started only a couple weeks ago.
Any help would be appreciated.
