You are not alone. I have also noticed the behavior you described recently. It also fails to find some movies that I know exist on IMDB.
Any help expected?
Wanted to chime in here... I am seeing the same issue, i.e., 1900 as the year, no plot and so forth, with the IMDB with AKA script. Please help with this since my Asrock ION spent the whole night scanning through some 1000+ movies and series on my NAS and everything was screwed up
