Sorry to revive an old thread. If this was discussed subsequently, please just let me know where.
I'm not sure how the TMDb API works, but on the website when looking at the various movie posters in the collection for each movie there is a rating and a number of votes. Could you default to the one with the highest rating? Or is that how it works already?
Again, I'm not sure exactly how MC17 picks which movie poster to go with but it has lead to some somewhat strange results for me. For example, for the Star Wars movies, Episodes IV and V have the new blueray poster, whereas Episode VI has the old THX DVD poster. The first poster to come up for Episode VI on the TMDb website is the blueray but that doesn't seem to translate to the Get Movie & TV Info option.
Thanks!
