Explorer thumbnail preview gone

[yomach]

Hey,
I've searched through the forums for this problem but couldn't find an answer.
I've a good codec pack installed, if i open a file in windows media player then it plays it without any problem.
However, no thumbnails are created in windows explorer for almost all of the files (for some reason, i'll get a thumbnail for about 1 out of every 30 movies, couldn't find anything special about those movies).

I'm running windows Vista, latest VLC player.
any suggestions?

Thanks

VLC doesn't do thumbnails. I would go away from codec pack and try just FFDshow.

Yea, i know vlc doesn't do the preview, but windows explorer does that (with it's own codecs).
But i've read around the forums that for some reason sometimes VLC screws that up, and since i have the right codecs installed but windows explorer refuses to make the preview, i'm coming here for help...

What do you mean by trying just FFDShow?
Remove the codec pack i have installed and install just the FFDShow codec?
edit -

p.s. - do you know if i need to do something for windows to dump it's old thumbnail cache and try to reload them (in order to generate preview?) or does it do that automatically?

Thanks

It should do that automatically, but unfortunately it can sometimes fail.

Yes,

VLC only replaces the icon with VLC cone if you use installer. It doesn't do anything for Windows Explorer.

Ok, managed to fix my problem, thanks.

I'll write the solution for future people searches.
basiclly this post says it all

It's a problem with x64 windows, the 64bit explorer cannot use the 32bit codecs.
The solution is to install the 64bit version of the ffdshow codecs
