I’ve been having problems whenever I browse to a folder containing video files. The thumbnails don’t generate and I was getting an error message “DLLHost has stopped working” or something like that. I upgraded to the Divx 6.5 codec and still got an error “COM Surrogate has stopped working”.
I finally found a fix.
It appears that the problem is not Divx, but Nero 7 (I had to upgrade because Nero 6 doesn’t work in Vista). Apparently Nero has been set as the default handler for xvid/divx files, so when explorer attempts to create thumbnails on the fly (when you browse to a folder containing video), it crashes and you get the error.
If you have Nero 7 installed, rename the file: C:\Program Files\Common Files\Ahead\DSFilter\NeVideo.ax to NeVideo.ax.bak but this will result in Nero Showtime being unable to play the video component. I don’t use Nero Showtime so I don’t care.
Now everything works fine.
