Suddenly (I think last windows update cause it) some of my MP4/MP3 files doesn't show tags (Artist, Title and Year) in Windows Explorer but I can see them in Mp3tag program on the same computer and I also see them in Windows 7 computer.
Also in Windows Explorer > View > "Large Icons" - those files have no thumbnail and there is no info on the length of the video or music.
This happened only to some of the files and I don't see deference with other files.
UPDATE: I used program mediainfo to analyze good and bad files and all bad files had a tag "WM/MediaClassPrimaryID".
