I posted this a few weeks ago but didn't get any updates. The problem is if I use particles to separate the movies on a disc (ie, the disc contain 4 movies), and add the cover art for each particle, when I view the movie in Theater View it first displays the particle cover art for the thumbnail then switches to the cover art for the last movie in the set created. Which means all 4 particles now show the same thumbnail cover art of the last particle.
The work around for this is to first use auto particles to get each of the titles, then get movie data for each one which loads the cover art, and when finished, go back to the disc from which the particles were created and assign the cover art to it. Then when viewing each of the particles, the thumbnail will first display the particle cover art and then switch to the disc cover art.
I tried using Rebuild Thumbnail but it made no difference. I also wiped the entire database and loaded only the one disc, but still the same effect.
Has anyone else been able to confirm this? If it is working okay for others then there must be something I am doing wrong or some configuration setting not set.
