coverart not updating

[LegioX]

I've been using YAMMM to download dvd covers for my movies and have found that in some instances if the wrong movie is selected and the cover downloaded, if I update it manually by replacing the folder.jpg inside the directory then NPVR doesn't reflect this change. The old cover is still shown. If I drill inside the directory then the AVI file has the correct image shown.

Windows shows the right thumbnails and if I open the folder.jpg file manually I can see it is the right image. I've tried deleted the thumbs.db file but this doesn't help.
I've tried restarting the services but this hasn't fixed it either.

Is there anything specific I need to do to force NPVR to update?

You could try emptying the C:\Users\Public\NPVR\Thumbs directory so it recreates the cached thumbnails.

That worked, thanks!
