Spanish thumbnail

I have 2 movies where the built in thumbnail software pulled down the image in Spanish. For example Cars is Carros. I removed the share from the media library. I then deleted all folders and that the wdtv created. I used WDTV Hubgen and got the correct jpg’s and xml. I then connected to the share without adding it to the media library however it is still showing the original image that the wdtv pulled down. How do I get it to recognize the new thumbnail? All my other movies work fine.

have you tried turning off your Media Library within your smp?
