Details not found

Hi,

I'm running into a problem and I would appreciate some help...

I'm using XBMC Frodo on ATV2 and Pivos Xios, library is stored in a mysql database and files are located on a NAS. When I browse movies with the XBMC Remote for iOS on my iPhone or my iPad, some movies don't have thumbnails. I refresh the movie within XBMC and once this is done, I tap the movie in the remote and get the message "Details not found".

Any help would be much appreciated.

Regards,

Khad
