It’s been some time since my video thumbnails doesn’t work anymore. Only some type if videos shows thumbnails such as: .wmv, .avi, .mpg
No other type of videos show thumbnails and mostly of my videos are in .mp4 format and in .mkv format.
I think it’s a software problem. I have installed on my computer: Media Player Classic (K-Lite codec), Gom Player, Power DVD. All of them are the latest version. I have tried uninstalling all the video players and codecs and then reinstalling, but without result. Can anyone help solve this problem??
