Huh? can't open video folders?

whenever i try to open a folder that has videos in it, i get an error message ‘explorer.exe has encountered a problem and needs to close’, then it closes the window, and does something weird like it refreshes the desktop or something. this only happens for video folders for some reason, not ones with music, pictures, or anything else in it. can someone tell me what’s up with this?

Try enter this into “Run …” from the Start menu see if it helps:

regsvr32 /u C:\windows\system32\shmedia.dll
